Ive done the library management before. For the moment I'm still content with paying for spotify premium. I bet they will raise their prices in the future to make me rethink that, but for now i enjoy not having to manage a huge collection and my spotify recommendations arent terrible yet.
Explains why Pandora turned out so great. At least when I used it ten years ago, then they restricted internationals. I could VPN and such, but at this point I'm just not vested.
