First of all, this list is obviously just my opinion. There may be songs that have sicker drops than these but either I've never heard them (in which case send a link or something to me) or I just don't have an .mp3 or something in my possession of a song with more badassery. ;)
These are all mixed by me so no sudden cuts -- all songs belong to whoever made them.
