Not sure if you've looked on Napster or iTunes, but there is precious little original AC/DC to be had. I wanted to download H2H (legally, even) but I couldn't find it. Anyway, I'm not the world's #1 fan but there are a few AC/DC songs that are in my all time classics -- the title, the title track for Back in Black, and You Shook Me All Night Long (Back in Black also). The rest of the songs are good but I'm not familiar with them. One thing that I love about the whole thing is the vocals and instruments all work together versus against one another and the sound works... crazy, but it sounds "natural."
