If then you want to listen to music during the boring bits, substitute good noise isolating (a.k.a. noise cancelling) ear speakers for the ear plugs & run them off an iPod or phone (source of yer music doesn't really matter - it's how / where the music gets to your ears relative to the source of the outside noise, ie wind).
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.
Wind noise alone, even in a "quiet" helmet, will lead to hearing loss.
Any music (or phone or radio or whatever) you listen to must come BETWEEN your ears and the wind noise, not from OVER it.
