"First you have to sign up for an account there and then and fill out the interview. Then it has options on your band administration page to add new songs, you click that and then click I agree at the bottom when it asks you about agreeing to the conditions, then you click Robust upload if your uploading the song from your computer to soundclick, then you click browse and find the song on your comp and then hit ok or press enter and then it will start uploading your song, it also has a blue progess bar to tell you how far along your song is, when that's done it will ask you for an image and you can upload pic or you can just skip that and it will put up a soundclick pic".
by the way -
you might get problems uploading when they're using the MS IE browser. i recommend Mozilla (the best browser!!!).
