Music can certainly serve to motivate
I'm also a climber and have often listened to music while bouldering because it helps me feel the flow, gets me amped to pull down hard, and can sometimes distract me when I'm a bit nervous on high ball problems. But I don't listen to music when I'm route climbing because the risks of making a mistake while 1,000 feet up are so much higher.
I can see how listening to music with earbuds at low volume could improve my boarding by getting me in a groove. But as a new boarder I try to be really aware of everything gone on around me. I think music might impair that ability.
When I get better at boarding and feel more comfortable perhaps I'll put on some Iron Maiden, Pantera, or Opeth.
