I use mp3unsigned No problems at all, easy to use, I prefer the presentation aswell if you are showing someone your work. Its free for the first 3 tracks and costs next to nothing after that. The sound quality is good and there is a volume fader on the player. Also, the music starts immediately, there are no problems with buffering. I prefer it over soundclick because of the look of the band pages and to my ear the sound quality is not comprimised. Check it out, I give it a thumbs up.
