So, it's pretty clear that Royce and I are pretty far apart in our tastes in music. Without any sound, you can tell he probably likes whatever the guy on the right is playing, while I prefer the group on the left. Now, I'm going to argue that songs played acoustically tend to emphasize the singer and the lyrics, while rock bands with electric guitars will focus on the music/harmony/melody and will even go into extended guitar/bass/drum solos just to hear more of the music some of these musicians are capable of. I'm going to further argue that Mr. Acoustic is more likely to enjoy a poem, being lyrics with no music, and Mr. Rock is more likely to enjoy Classical music...all melody, no lyrics. (Especially when it includes cannons or explosions)
You see what I did right there?!? BAM!!
