We recommend that you allow us to deliver your release to all digital music stores available from within the app, including Spotify, iTunes, Apple Music, Deezer, Tidal, Google Play Music and Amazon Music. All the stores are pre-chosen but you have the opportunity to choose if there are stores you do not want us to distribute your music to.
The only reason not to choose all of them is if you have a prior agreement with another distributor for a specific market.
Don't be mislead and think that 100 stores is 10 times better than 10 stores. The top 10 stores are likely to account for 99% of your revenues. So distribute your music to all the stores, but focus your efforts on promoting on the stores that pay you the most.
YouTube differs from the other stores as Amuse delivers the tracks not for uploading but to claim the recording for the artist. When we deliver music to YouTube, they will provide a system called "Youtube Content ID" that will claim the copyright of your music.
