sustained wind noise, much less music loud enough to be heard over it will damage your hearing. What you need to do is to bring it down which ear plugs and a good full-face helmet will do. If then you want to listen to music during the boring bits, substitute good noise isolating ear speakers for the ear plugs & run them off an iPod or phone. At the moment I use Weston UM1's, good low profile (so they fit under a helmet), high isolation ear speakers with very neutral sound.
