For me, my favorites are: Back In Black; click, click, click, click, click, click, CLACK CLACK! And when that heavy E chord first hit, the intro instantly became a classic. Next, I love the starting riff of 'Sweet Home Alabama', Idk, but there's just something about that clean tone I guess. Next-next: Blue On Black (not to be confused with above). This one, a lot of you may not have heard, but it's by Kenny Wayne shepherd; I think I like it because of the heavy drum beat, which perfectly accompanies the driving blues-rock beginning. Last, but certainly not least: 'Mary Had a Little Lamb'. The SRV one of course.
