Cool, subscribed! Reminds me of a site I started a couple of years ago called 1SONG. I'd have people subscribe and then send them one hand-picked song per day by email. They could then stream it on all the services I could find. It leaned toward electronic and hip-hop music. I had it all automated once I selected the songs to send the emails and load the content into the html emails by RSS.

You can see its remnants at http://1song.co. All the artist images are missing currently on the Wordpress site so it doesn't look the same. I even wrote up little blurbs on each song.
