If you've been dating a girl for a while, a guy can get a pretty good idea of what kind of music she's in to. Want a little secret on how to get some brownie points? Make them a personal SYNC playlist - whenever they hop into my car, I just say, "Play for Lovely" and all her favorite songs come up. It's like this generation's boombox outside the window. Of course, I make personal playlists for my buddies too but...she doesn't really need to know that.
