Do you approach music with any particular kinesthetic sense? I've had some great conversations with other vidders who hear music as color (one visual/graphic artist in particular) and some (like me with more affinity for dance) who hear it as movement. A song has an underlying feel for us. Is there some way that you relate to music beyond just the lyrics and the tempo? Depending what your source has available you can even get away with an instrumental piece if it feels the right way.
