YouTube Music is trash. Deletes songs

Title says it all. So I just started to notice that you only get a limited amount of songs you can play from your liked list a time.

Take for example if in the he time you have had YTM, you liked/saved 300+ songs. You can only really listen the he time 150 of them at any one time.

The older songs you liked will be rotated put of your liked list over time and you will have to re-like them to get them bumped up your list.

I switched to them form Pandora because of the small library they have there and YouTube is HUGE.

But that's the point of liking and saving songs if YouTube only let's you listen to the ones they want you too.
