But the underlying issue is that those DJ tracks many times technically did need permission from copyright holders to be posted. Unfortunately dealing with this w/o a ton of money is just a failing exercise.

Soundcloud is still good to get DJ mixes from DJ's I like, but I can seeing it go away just due to all of the costs that would accompany trying to ensure they have the right to share everything that is posted by users.

What the parent and I are saying though is that DJ mixes were a small part of the content in the early days. It wasn't created to host DJ mixes or marketed as that initially. Producers/songwriters/amateurs were the bulk of the content. SoundCloud could have built a decent business by banning copyrighted material and only dealing with original works. There was never any need to get into the messy licensing business.
