...Neither? I'm not a big fan of music with lyrics unless it's in a language other than English, tbh :3 But if I had to choose, I'd go with Panic! 'cause I know my cousin liked it at some point and she's cool so yeah XD;
Brass (trumpet, tuba, french horn, trombone, etc.) or woodwinds (clarinet, flute, saxophone, piccolo, ocarina, etc.)?
First thing I could think of besides something Fairy Tail-related; doesn't help that I need to practice my trombone tonight.
