What is trap? Tranny-rap?
From urban dictionary:
In laymens terms, Trap music would be best described as a recipe;
1/3 hip hop (tempo and song structure similar) however vocals are usually pitched lower or higher
1/3 dubstep (similar drum arrangements, different builds and drops)
1/3 dub (Low frequency focus and strong emphasis on repetitiveness throughout a song)
Dont know if that helps.
