I listened to SPG last year after I saw them at an autograph session at Youmacon last year. I would have to say one of my favorite songs by them would be
Automatonic Electronic Harmonics; I'm a big fan of the harmonics in that song <3
I can't say if I really like them or not which is weird. They aren't a band I would listen to as often as say Disney music or even All Time Low, but I don't hate them. I guess they're situational?
If they go to Youmacon next year, I may attend their concert as I heard those are very silly.
