Hey guys, these chords are done by request, so I hope others will enjoy it as well!  
comment and rate!

The song really only plays the F#m chord during the verses, then just the notes (A, G#, 
after it, but it sounds okay if you play the chords as well.  Also, the pre-chorus only 
notes, but once again, the chords sound fine.
