lots of anime threads, but let's use this one to focus on soundtrack.
There's lots and lots of anime with great ost, Naruto, FMA, FMA:B, Death Note...
Then there's some with only few awesome soundtracks but overall is mediocre, like HxH 2011.
You can post examples of good soundtrack.
My vote goes to FullMetal Alchemist, it got one of the best anime soundtrack ever , no one can say otherwise.
The other songs are great too, it even has Beethoven!
Right now, the one I like listening the most is unfortunately it's one of the only three songs I really like in that anime, others are really annoying.
