It'd be a lot easier to hear if there was more distinction between the two voices. However, it seems that at lease he understands having a range which is unfortunately often overlooked by many vocalists. I'm still a bit confused by your PS statement though. If he knows he sucks, why did he do it? I wouldn't say that he "sucks" but it's just a little difficult to distinguish between the voices and AILD isn't very technical vocally speaking. Like I said though, they're good to practice pitch range to on certain songs if that's your style of music.
