smart - Is my hard drive failing?

I'm beginning to worry about my ~3yr old WD Green drive. In the last few days i've noticed that my media player is acting weird, it won't move to the next track after a song has finished and also won't play new songs when I double click.

So, I downloaded the "smartmontools" package and used "sudo smartctl -a /dev/sdb2" to check out the drive. Here is a snapshot of the output:

I'm worried most about the "Pre-fail" rows.. does this mean that the drive could fail at any time or what?
