Do lyrics make a big difference to you guys as well?
Yes, I like the lyrical component to music very much, but I like instrumental music aswell.
While people like lyrics because lyrics convey meaning to them, I think instrumental music still conveys meaning.
Lyrics that are especially surrealist, humorous, cryptic, and well delivered (all at once) I like very much. That is part of my appreciation of artists like System of a Down and Frank Zappa.
