The problem with Soundcloud is that grew too big and as a result aren't building a site for their core customer: indie artists. Take a look at the front page, all it shows is tracks and artists that are already hugely popular. The features they are focusing on seem to be a hodgepodge of things taken from Spotify and Last.fm, but without any real value-adds for someone who's just uploading music. I recently made an account for a new project I'm working on and all the organic traffic I'm getting is just spam. Bandcamp is now the place for unsigned artists to go to promote/sell indie music.
