Lyric discussion by UUTR 

The reference to Robert Johnson is much deeper. The legend is that he sold his soul to the devil and got guitar skills for it instead. However: 'He got the real killer groove Robert Johnson and the devil, man Don't know who is gonna rip off who' Johnson is so skilled that he can beat the devil. Like people that found the god particle and could (once) surpass god.

Didn't know this, thanks for clarifying! I feel like another jigsaw falls into place.
