Facebook: where's the social recommendation juice in your App Center?

Facebook just launched its App Center.

“The App Center is launching tonight with more than 600 social apps, including Nike+ GPS, Ubisoft Ghost Recon Commander, Stitcher Radio, Draw Something, and Pinterest” 

As I'm a music lover - have hundreds of music interested friends & use quite some music apps on a daily basis - I thought Facebook would be able to guide me to some interesting music apps, I haven't stumbled upon myself.

Well, that's what the first real social app store got to offer me.
