It seems like there's a new way to distribute online music every day.

The latest model, according to PC World, is basically a collection of subscription Internet radio stations that choose songs based on your stated preferences. There are a lot of great free Internet radio stations, but this one appears to be commercial free and ideally will do a better job of playing songs you like. Hopefully it will do a better job of picking songs for you than my TiVo does in picking shows to record for me (why does it continue to think I like Telemundo soap operas?), but it has a thumbs-up/thumbs-down feature like TiVo so it's trainable. At only $3 a month it's cheaper than Jim's satellite radio and my Napster To Go, although both of those offer portability. Bottom line, different price points for different benefits, as you'd find in a vibrant market.
