I burn MP3 CDs for my X. No ID tags though. Almost completed installing Sirius Starmate replay on my Ashtray via AUX according to Howto's here. I've done my research however it is lot harder than descriped with so many variables.
Most advanced way of listening music will be streaming via Pandora.com it creates a stream of music using Aritficial Intelligence, I hope I could listen to this in my X someday. FM radio is really bad at where I live!
