Hey, did you see the new music bloggy thing in the right hand panel. I've got some albums uploaded to it and you can play them by selecting the relevant playlist. There's some Bob Dylan, Neil Young; Carol King and Joni Mitchell. there's also some ZZ Top for the more heavy minded and yes the great Cat Stevens. You need to click the library flyout above the albums to use it. Click on the radio or click on a playlist, clicking on the album covers doesn't work.
I have stuck a whole pile of classical stuff on my radio. If I can get my microphone to work I might try my hand at creating wee radio shows just for fun.
