The best way to listen to Sirius on the web. Lot's of cool features, the album cover view and MP3 recording are nice touches I don't even get with my hardware Sirius radio. The only thing my hardware radio does much better is change streams faster! Interface is not as pretty as SiriusMac but easy to use and mostly easy to figure out (tool tips would be a nice addition - if I had those I would have been able to figure everything out faster and without having to visit the official forum). I look forward to future releases. Tip: make sure your system volume is reasonable because it always starts at max volume!
