Music replace

Can't understand why you even would want to replace it. Granted I'm also tired of the A3 town theme, but that's about it, even after about 1000 hrs music is always on, even when playing in party, I think it's brilliant.
One time I tried to follow the nostalgic people and played with D2 music, you know what, 80% of it annoyed me, the other 20% activated some nostalgic brain cells, but overall, not worth it at all ! PoE music rocks, I could stay in the catacombs forever :p
