Pay no mind to my last tab, I listened to the song again and realized it was completely 
this is how I really play it.

listen to the song, you'll figure it out.)

sorry about my last tab I got mixed up about the chords and was one step off this one 
much better. (My last tab might not have even showed up on the website anyway, which I 
it didn't) but anyway I'm really new at this so sorry if this tab sucks but I gave it a shot.
