~~Apple Music web isn't working on Vivaldi, which settles it, I'll have to use Spotify on desktop I guess.

Yes, Widevine was working on Vivaldi.~~

turns out, you can just restart the computer and it'll work. Also used Chromium (which needs Widevine to be installed, chromium-widevine is the AUR package you need), but I fail to see how this'd affect Vivaldi.

@Flaky Maybe try https://www.qobuz.com/ ?
There is a native Linux app (but not an official one). It's here: https://qbz.lol/

Qobuz
@arutaz Already did via a trial, wasn't my cup of tea. I do use Qobuz for buying my music though.
@Flaky Ah ok. Same here, I buy my music there
@arutaz Yeeee, Qobuz and Bandcamp are my go-tos. 7Digital is also one but I'm concerned with the merge with MassiveMusic. Seems like its days are numbered, which is a shame since they're cheaper than Qobuz.
@Flaky Ah, yes I've used those also hehe.
