Artist: Bring Me The Horizon
Song: Diamond's Aren't Forever
Tuning: Drop A#
(A lot of the rhythms aren't exact because its too hard and time consuming to
tab them exactly. Also, I don't use any programs to tab songs, this is all done in 
Notepad so if there are little errors in how the tab is written, ignore them.)
