content: Basically it was an upload site for music. People could upload music and anybody could search and listen to it directly in their browser. They somewhat got away with it because it was "user uploaded content" and they would comply with DMCA requests. However internal e-mails showed that staffers would re-upload the DMCA'd materials and that's why they got shut down. Imagine it like Spotify, except the users uploaded the music instead of the record companies. Also there were no advertisements (Disclaimer: I use uBlock Origin, so there might have been ads, I just never saw them.)
