Really digging Spotify so far. My only gripe is the amount of ads that try to get me to switch what I am currently listening to, especially when it is a completely different genre. When I'm listening to the Talking Heads, I don't want to hear some new hip hop song...at least let give the ad a thumbs down or tell you if the ad is relevant to me. I figure Spotfiy would do well to craft some sort of a personal ad profile for everyone using the free service. After all, the happier their free customers are, the more likely they are to fork over the $5-10/mo for the premium services.
