Songs that are no longer available are playing with no sound, and shuffle isn't that great

Hello,

My complaint is that on mobile, with the random shuffle playlist, songs that are no longer available, such as Taylor Swift's songs, are popping up and being played, but no sound comes out of it, forcing me to waste a skip.

I feel the shuffle algorithm can be improved.  For example, I have 242 songs on a playlist, but I hear about 50 of them regularly on shuffle mode.  I can try to keep an actual tally for more information if it is wanted, but I keep hearing the same 5 artists on shuffle out of around 75.

Thanks.
