I think there should be separate section thingys for discussion of Music, Movies, Books and such.
They usually go down well in other forums I have used.
Everyone likes talking about those things =D
Posting threads about such topics in general discussion places usually get pushed to other pages before anyone posts anything because there is a lot of things to say in general discussion =(( (or 'anything goes') and it clutters the threads and such.
Just a suggestion though, I guess it isn't really 100% necessary at all.
