3. Releases: Audio, artwork and title data

The artwork of your release must meet a number of requirements:
- The image must be square.
- Minimum size 3000 x 3000 pixels, maximum size: 5000 x 5000 pixels.
- File format: jpg, tiff or png.
- Colors: RGB.
- Maximum file size: 36MB.
- Title and artist mentions must fully match the metadata of your release. In other words: an artist name or (sub) title that is on your artwork must also appear in your title data. Do not place additional information on the artwork.
- Titles and names of artists must be clearly legible, even in a small format.
- Pornographic, discriminatory or offensive images are not allowed.

The following data may not appear on the artwork:
- Addresses of websites
- Contact details of the artist
- The 'role' or instrument of the artist ('piano', 'producer', etc.)
- Logos of download stores or streaming services
- Logos or names of companies that have nothing to do with the release (logo or name of your own label is allowed, provided you also use the label name in the title data)
- Price information
- Years (unless they are part of the title or stage name)
- UPC code (barcode)
- References to the format of the release ('single', 'album', 'LP') or other physical properties ('Limited Edition')
- The track listing
- Texts that do not appear in the title information

Never use third-party images without prior permission.


We accept audio files in the following formats:
.WAV, 16 bit, 44.1 Khz, stereo
.WAV, 16 bit, 48 Khz, stereo
.WAV, 24 bit, 44.1 Khz, stereo
.WAV, 24 bit, 48 Khz, stereo
.FLAC, 16 bit, 44.1 Khz, stereo

Other files (mp3, DDP master, etc.) cannot be processed.

Any silences at the beginning or end of a track may not be longer than ten seconds.


Yes, when creating a release you can indicate the desired release date yourself. Keep in mind that most stores need a few working days to import and process a release. Our advice is to send releases at least ten days before the desired release date.

An indication of the processing time of each platform can be found via the overview of the available stores.


When creating a release you can choose under which genre it should appear in the stores. The stores are free to choose a different genre, but the preferred choice is usually adopted.

Choosing a 'primary genre' is mandatory. By entering a 'secondary genre' you can further specify your choice, but this choice is not visible in all stores.

You can find an overview of all available genre options here..


The layout of genres and subgenres differs per store. Some stores use a few dozen main genres, while other stores make further subdivisions into subgenres. Furthermore, there are sometimes differences in genre designation per country or continent.

The genres you choose when uploading your release are therefore preferred. Stores can reserve the right to adjust the (sub) genre according to their own wishes.


Artist names and album titles that are written in UPPERCASE are changed by some stores to the regular spelling: an uppercase letter at the beginning of the name and, for the rest, lowercase letters. An exception is usually made for abbreviations or non-existent words. We cannot influence this.

Spotify and Google Play Music generally accept artist names written in capital letters. If they change the name to lowercase, we can submit a request to make it uppercase. We must, however, pass on links to social media accounts (Facebook, instagram), on which the name is also written in the desired way. If you use a different spelling for your artist name, we therefore recommend that you apply this consistently to all your public profiles.


Yes, distribution of a compilation / compilation album from multiple artists is no problem.
A release is considered a compilation when four or more artists ('primary artists') participate.

In this case, on tab 1 you enter “Various Artists” under 'primary artist'.
For the individual tracks, enter the actual name of the artists.


You can add names of composer, songwriter, producer and any other roles via the drop-down menu under 'primary artist'. This option can be found on tab 1 (data for the entire releases) and on tab 3 (data for individual tracks). Don't forget to click on the 'add artist' button after entering the name.

Add roles


Yes, when filling in the data for your release you can enter your own label name or company name. This is visible in almost all stores. If you do not enter anything, WM Digital Services will be listed as a label.

You can add or change the label name on tab 1, “Release info”.

With each release you indicate in which language the songs are sung. Of course this does not apply to instrumental tracks. Therefore choose 'no linguistic content' for these tracks.


When uploading your release, you must indicate whether it contains “explicit lyrics”. These are texts that are sexually explicit, contain swear words or curses, or are otherwise unsuitable for minors. In some countries - especially the United States - it is mandatory to indicate this in advance, so that a warning can be placed in the download stores for the relevant release. You can compare it with the Kijkwijzer for films.


When you have none ISRC's (a unique code for each individual track) or UPC (a unique code for the entire release), that's no problem: these codes are automatically assigned to your release after it is sent to the stores.

Do you want to start using your own set of ISRCs? You arrange that via SIGN: isrc@sena.nl.

If you do have ISRCs and / or a UPC, enter this in the correct place in the title information.


The 'reference number' (tab 1 of a release) is a number for internal use, which is generated when your release is definitively sent to all platforms. You do not need to enter anything here, so the option 'I don't have one, please assign a reference number code to this release' can remain checked.


The Global Release Identifier (GRid) is a unique code for digital releases, used by some platforms. The multiple artists do not have this code themselves, so when entering the title details, you can skip this field.


Does something appear to be wrong with your release after it comes online? You can change a number of things via your account, eg the artwork, the title of your release (provided it continues to match the data on the artwork), song titles, the label name, the genre, the sale price.

Business that CANNOT can be changed are:
- the stage name (exceptions are possible, email in advance for information)
- the audio files
- the UPC and ISRC codes
- the order of the tracks and the number of tracks

After making the desired change, resubmit your release to all platforms it was originally shipped to. You do this via the 'update' option on tab 6 of your release.

Keep in mind that it takes some time before all platforms have processed a change. Is your change not visible after 14 days? Then take it contact us.
