Ad Revenue Programs other than Google Adsense

Tweet

I am currently running a music site and was primarily earning from Google Adsense. But due to the recent modification of the terms and conditions of Google Adsense where it strictly disallow putting their ads on copyrighted materials, I had to remove it. I don't want to violate the TOS since I am also running it on my other sites and blogs. By the way the reason why I removed the Adsense code is my site contain lyrics. My site generates good traffic. I get around 200 unique visits per day. Which other programs can you suggest?
