Re: fill my iPod
Mahavishnu Orchestra. Check out One Word, Birds Of Fire, Meeting Of The Spirits and The Dance Of The Maya.
The Raconteurs (Jack Whites side project, very good blues/indie/rock)
I think some one else has said Battles but I second them, if you can get into it their music is amazing
Also check out some podcasts to fill some space with. Their free and if you find a good podcast its really something to look forward too. Check the iTunes store
