Another melodic riff that's kinda similar "My friend of Misery" by Metallica. Newsted was always cool to me. He was all about metal, but he could create really melodic basslines as well. I'm sure everyone else is going to name off the local heros like Jaco and all those jazzy guys (I'm not putting them down), so what the hell, Continuum by Jaco is kick ass, but I don't think I'll be posting an MP3 of me playing that...
