If I had to pick a favorite instrument, it'd have to be bass. When there is a great bass line, (funky or dirty usually does the trick:) I love the song. No exception. I often wish I played bass and entertain the idea of learning (if only I had a few more hours in the day). Well the riff for "One Way" is definitely more like a bass line. It's very simple and I had a blast putting a melody to it.
