Genres helped by Manhattan: Classical, jazz, rock, of all kinds, any 2 or three chord music such as non pop country, blues. Even pop music if you can get by the autotune.
Genres not helped by Manhattan: techno, rave stuff, many forms of electronic music not based on melodic western musical theory, rap, pentatonic or most traditional forms of Asian music such as Chinese opera, pre-medieval western music, and that form of classical music based on twelve tone scales (Second Vienese School).
In short, if it is western music with conforming scales, you are probably OK.
