This is a problem I never had a possible solution for. I would like to have Youtube Music in a separate (pinned) tab, but in the same window as everything else. The problem I have stems from youtube/google: I have 2 youtube accounts - once under my username, and one under my real name, and I don't remember how I ended up with that. I normally only use the account with my username and the "real name" account is mostly unused. But when migrating from Google Play Music, youtube decided to force me to use the "real name" account for that, and that's what I'm stuck with now. So I would like to have youtube music, which need to be on account #2 open, whhile all other tabs are on google account #1. And when on the same profile, this is simply not possible. Switching account on one tab switches it for all others. Is it possible to do that without a separate window open just for youtube music?
