a while back, in the pursuit of a good internet radio station, i discovered pandora. it's a free, commercial free internet radio station that you customize. you type in a band or artist you like, and pandora searches for other similar bands or artists that you would also like. you can rate each song, so it won't play the ones you don't like. the best part is that it's free and commercial free. i didn't think that existed anymore! you can upgrade to a paid subscription that removes the ads on the site, but the ads don't bother me since i'm not staring at the site all day. i usually just listen to my sansa at work, but there are days when the battery is dangerously low. one of the cons of the sansa is that you can't charge it and listen at the same time. so while that's charging, i listen to pandora. another great way to discover new music!
