Trying to learn bass guitar

I've been tinkering with the new bass guitar. It's a totally different animal than the guitar. Needless to say, I have much greater appreciation for the pros =)

I've been working on the song "White Discussion" from Live. It's one of the songs Ben, Tyler, and I picked out to learn as a group.

Here's my newbie attempt: bassfun.mp3

I'm finding that it's really easy to get sloppy on the bass. Seems like the goal is to play clean and tight.
