I hate that I can't search my own tracks that I've uploaded anymore. I tag/title my tracks such that I can find them later. Well, the new interface killed that - now I have to search the entire site to find my own damn tracks. It's silly.<p>I love that I can embed SC on most any forum.
HATE the new SoundCloud, but LOVE that the song continues playing wherever you navigate on the site.<p>HATE that they limit the total duration of files you upload, rather than total size of files (although this way they save money on server space).
Would be cool to be able to transition between different "sounds" in a "set" - right now you can just tack them together with nothing like a fade in/out.
