Need help with Adrev and Conent ID

I’m new to this. I’ve submitted my application on adrev but this is their reply:

Hi there,
Unfortunately, we cannot work with your library. Please find another aggregator in the lists below. Thank you.

can you help me? Same issues with Content ID

Hey. I’m curious as to why they won’t work with your library. If you’re still looking, then I’d recommend Haawk. They are pretty cool at managing music and all the rights. Check them out and let me know what you think!

I’ve also heard of Muserk, only 2 users are using it though…

Apparently no one is using Haawk here. What other alternatives do you recommend?
