The top song of the past four weeks("Thrift Shop") contains the notes: Gb,Ab,Bb,Cb,Db,Eb,F. Yep that's a Gb major scale,no biggie...but the cool part is that the song revolves around the Ab note. Typically if a recording contains the notes of a Gb major scale, the recording will revolve around either the Gb or the Eb note, but this one doesn't. That's why it's cool.
