I had Red/Premium as part of my Google Music subscription, but they decided to kill that.
I assume YTM is far inferior to what you had? That's bundled with my premium, but I don't use it much on account of Apple Music's integration with my own longtime music library (which, ironically, I remember GM being also strong with letting you upload your own collection)
If you just aren’t into “short form” video (or what used to pass for short until TikTok came around, lol) I can see how it would be unappealing to pay for a site you don’t use much, but YouTube premium is my ideal way for media to work.
