Despite playing the first tracks much more than the later tracks on most of my CDs (I'm a habitual cd swapping junkie), the latter tracks on my CDs tend to fail before the earlier ones when the things starts to get beat up. I would assume that an 80 minute disc burnt to the rim of the platter would fare worse than a rip-off weezer album.

I don't know why this is, exactly, but there is definitely a corrolation between length and failure, at least in my experience. Wow, that has some interesting sexual meaning as well!
