I've actually had a few songs done for quite awhile now, but I'm still looking at hosting options. There are many out there, and some charge a percentage... some charge a monthly flat fee. Most charge for downloads - but some don't. I think I'm pretty clear on which one I'm going with - it's just going to take some time to get it up and running. I think some of these sites are great if you sell a song once in awhile, but if you sell a bunch, it's better to go with another. Soon though.
