As for moving your playlists, I use this app. I bought a perpetual licence for it years ago and it's so handy. I used it to move all my stuff from Spotify but I keep it installed on my phone for whenever someone sends me a Spotify playlist, I can just copy it to YouTube Music in seconds. Source: 6 months ago

Congratulations on the launch. It's great to see work in this space. At the moment, I'm using https://freeyourmusic.com/ because I have playlists on apple music, spotify and youtube. - Source: Hacker News / 10 months ago

There are a bunch of services that will move your music library for you. I use Free Your Music but there might be newer/better options since I bought it. Source: 12 months ago

There are a ton of transfer services out there, SongShift is one, FreeYourMusic is another, they aren’t perfect but will get you 90% of the way there. Source: about 1 year ago
