It's all about changing the tuning of the guitar. Open E is standard, starting at the 1st you can change the key and fret as usual but the chords are now different depending on where you have it. Too much music theory for my little brain. I just play.
ha, funny how people are different,.. the song's new to me, (not really my niche), damn thing's stuck in my head, I've listened to it a half dozen times since last night,.. I admit It would be a good song to put on a loop to torture people with.
A song that sticks in your head and won't go away is called an earbug. Fortunately when I get an earbug it's a song I like that is new or at least new to me.
