I do a weekly podcast playing totally independent artists called Is This Thing On? available on Itunes ect.
If you want to have your music played then follow the instructions on the blog http://isthisthingonpodcast.blogspot.com/
Don't send me links or ask me to visit your site, I'm just too busy.
827 subscribers and around 150 random plays a week.
Loads of features, information for non signed acts as well plenty of content for non musos and often very funny!
A community of music explorers and artists playing the best music you never heard.
