Two part for me. For new riders or someone still becoming proficient, their situational awareness is still being "tuned". These riders need to commit 100% of their senses to riding. No music.
For long time proficient riders, their situational awareness is already at it's peak. You know if you are going to take away hearing, you need to compensate by scanning more with your eyes. The main audible cue you can't see is a horn, but you know from experience why people use their horn so you translate that into visual cues. You can afford to do this because operating your bike is like moving the fingers on your hand... it's become natural. Music is ok.
I seldomly ride with music. I occassionally listen to music while riding the hour down to the track, but most of the time I just wear earplugs.
