This is my favorite mash-up of all time, made from the songs Radioactive by Imagine Dragons and My Songs Know What You Did in the Dark by Fall Out Boy, mashed by AirGirlPhantom on YouTube, link here: https://www.youtube.com/watch?v=eR99ubyBCGE. Sorry about the capo, but trust me, you don't want to play the chords I came up with without it. Also, for the most part, Fall Out Boy is on the left, Imagine Dragons is on the right. Tempo: 140 Chords Used: Am, C, G, D, Dm *Capo on 4th fret*
