Whilst gaming? Hmm for most games I would listen to the soundtrack on the actual game, but I'll admit, some games have a bad soundtrack! SoundCloud has some okay lists, but probably just my albums on iTunes or some playlist on Spotify. I buy some things from Bandcamp occasionally, as I think they give a better percentage than iTunes or Spotify.
Oh, yeah! I would say they are rather annoying! Especially the ones that have the same melody on repeat.
Honestly, you gave some good ideas! I've also heard some good feedback on Bandcamp. Some of my friends are currently using it and say it's okay. There's a list of platforms that caught my eye. It covers some of the ones you've mentioned. However, I am more interested in The Future FM. It has some nice DJ mixes that might change my gaming experience for good I don't know about you but I love me some good mixes, and the ones I got the chance to review sounded promising! Have you heard anything about that platform?
