Well, soundcloud has had financial problems forever, so I’m not surprised they are going to tighten up the free accounts.

I have a paid account there which allows me more space than I’ll ever use, plus I can update mixes which I do from time to time.

But I much prefer reverbnation, sound quality is better IMHO, site looks better too. The free reverbnation account has no limitations on the amount of songs you can upload. There is a file size limitation on each song, forget what it is off the top of my head, but for most songs less than four minutes I found I could upload a 256K MP3 and still be under the limit.
