One of the best record stores I've visited in recent times is the centrally located music store, Dense, in Berlin. Their selection is impeccable, their staff friendly and they know their music. I've visited my share of music stores around the world—including Ameoba in L.A., Tower in Tokyo, Kim's in New York, and the recently dissolved Smallfish in London—and I have to say Dense is definitely up there. Their electronic section is very well sourced, they have great vinyl and they don't stock any commercial music. If you ever find yourself in Berlin, make sure you head to this store for music you've probably never heard of.
