I would like to upload mp3s (of music I hold the copyright to) to my WordPress blog which can then be streamed. I would also like to be able to make people enter their email address before they can download them. I have seen this on other people's web sites, but i'm not sure whether it can be done on WordPress.com. Can anyone tell me whether there are any 3rd party widgets or plugins I can use on WordPress.com or whether there is already some way to do this on the site?
The blog I need help with is freegardeners.wordpress.com.
