Sometimes my belly really gets in the way when I'm playing at times. This also means that i have to lean a little bit forward to see the guitar neck when I'm playing difficult parts, and this song had a lot of them. My belly always pushes my guitar a little bit out my view when I'm playing, It can get really annoying at times. But i also think that it have helped me become a better guitar player at the same time by not watching what I'm playing.
I also had this weird issue that i kept breathing my hair into my nose all the time when i was head banging.
