Alternative and indie rock mostly, with some 3rd wave ska, punk, and 80's rock thrown in for good taste. Every now and then i'll go old school with some J. Geils Band or The Who. Anything other than country and opera has a chance for getting my approval, but I don't give just anything the 'thumbs up'.
Satellite Radio is the best thing I've purchased in years; I never have to worry about finding a signal, and can ALWAYS find something good to listen to. (Sirius=good. XM=bad.)
