Hi, I don't see any reason why you couldn't switch to Google adsense as your not actually doing anything illegal from what i can. Its just a site with links on it your not actually yourself sharing and songs. I have seen many sites like this before and they all serve Google Adsense ads and they seem to be doing fine. Thanks
The Best idea is to get reviewed by google team. Do one thing, just go to adsense support forum, then post a question, whether your site is eligible or not, so that google team will tell you result. So, if they said yes, you can earn lot. Why dont you experiment friend?
