Thats funny because my guitar instructor was telling me yesterday the importance of feeling in music. It can be the way you pick the strings, like when you pick hard for an angry sense, or smooth easy picking for a softer emotion. You can have two awesome guitarists, all never missing a note, (playing the same song), but if none of them have any emotions, its boring. Music should touch you on the inside, however corny that may sound. We all have different tastes in music cuz we can relate to the feelings, how it makes us feel.
