How do I prevent Apple Music from removing songs?

Hello,

This is a user to user forum, you are not addressing Apple or Apple Support here, only other users like yourself as such, nobody here is removing songs from the Apple Music subscription service catalog.

For that matter, neither is Apple, in most cases. Unless a song or artist has violated the terms of service of the Apple Music subscription service which is fairly rare, Apple does not actively remove things from the platform, sinmply because they do not own them and its not really up to them whether they are available or not.

Artists, music labels, studios and rights holders however can and will remove tracks and albums they own or have the rights to for many reasons and without warning.

If songs and albums from your favorite artist are going missing, then its almost assuredely that they are the ones removing them, either to upload better masters, new versions, distribution rights limitations, or for many other reasons.
