website looks great! Just a suggestion, if the ad at the top is a 468 X 60 banner, make sure it shows text and images. If not, diversify your income and choose another ad service to always show a banner at the top. Maybe signup at commissionjunction.com and find some ads related to music.
I haven't had luck with any banners on any of my sites. I use text ads only. This includes CJ partners. Rather than using banners, write your own Adsence looking text and link it with your CJ ID. My 2 cents.
