My goodness! I am sitting here as we speak *vibrating* lol....my neighbor has their music that loud!! I don't wanna call the cops but I mean come on!!!! We live in townhomes and it's 9:30 at night!! and all i can hear is "booom!! BOOM booom!!!" Do you think the cops would tell him who called? I don't want them to hate us and do it even more you know?? Last time I even tried playing the Spice Girls really loud but that made him turn his music up even louder lol!!

No, the cops will NOT tell him who called. They will only say something like "We've gotten a report that your music is too loud, turn it down". Possibly also say something about disturbing the peace citation if they have to come out there again.
I'd call. Even if legally they can play it loud until a certain time like ten PM, there is still a nuisance ordaince in most residentual areas in the US. Call the police and ask them.
Luckily where I live, we have managers who also live here, it's law in complexes with more than 15 units to have on-site managers. I don't have a problem with my upstairs neighbor with loud music, probably because it is a relative of the managers, but I do once in awhile have to call them because there's cars blocking my carport, or someone's kid is screaming in the laundry room. (my dining room faces it, normal doings in there I expect, but screaming kids playing in there is a no-no).
Good luck!
