XM satellite radio: how did I live without it?

I finally succumbed because of the baseball: every team, every game, all season. And I'm loving that. Increasingly, though, I'm enjoying the regular radio programming. Example: Ethel, channel 47, is one of the 100% commerical free music stations. Their last five songs: two Modest Mouse songs, then a Pogues song, then a random Sublime song, and now Primus. Fun stuff.
