Recently I have been listening to this music called “trap music” at least that is the name I have heard thrown around soundcloud. The genre still seems kid of ill-defined and young in its age because it still does not have a wiki page. However, there is a T.I. album titled “Trap Muzik” which might be some indicator. Anywho, here is the urban dictionary page if you are curious, the definitions are pretty interesting. The top one seems like it would be the most accurate but you can never be sure with urban dictionary.
