Not that it matters too much, but why did you call it Beluga? Beluga is a pretty famous Facebook acquisition, and is the first thing I think of when I see Beluga, besides the whale!
We really like using aquatic references at Grooveshark, and since the beginning this project's code name was Beluga. We really liked the name, and, since Facebook absorbed the Beluga you're referring to for their talented employees, we decided to keep the name.
