I've considered Spotify premium only because itd be convenient to have it in my car or when I'm not home listening to music. Or its easy to type up on the program/app and load a quick song or album. But it is kind of annoying how some stuff is not on Spotify.
Rarely do I have that problem but sometimes I do, like Gong's "Magick Brother" not being on there for some stupid reason. Either way, I still stick with soulseek but mp3s/FLAC etc (digital music files basically) are becoming more inconvenient and a pain compared to streaming. I still like to keep a collection though.
