the tags are really decent, like the previous poster said it's pretty much all audiophiles so everything is tagged, a lot of FLAC stuff but you can sort by MP3 (Nicotine+ makes it really easy in that regard)

The great thing about it and because the user base is mostly audiojunkies is that you can find some REALLY obscure stuff. Like things you'd never find on spotify or youtube music or any of that. I once found a set from a band I love from a show I was actually at.
