i'll tackle some of this for fun
van halen: fun band until DLR left, DLR was the prototype for every other cockrock band that came out in the 80s, Vince Neil and Brett Michaels wish they were DLR, he was probably my favorite front man for this type of music, some favorite songs include Unchained, Panama, I'm the One, On Fire, Hot for Teacher
motley crue: the best cockrock band if you dont include van halen, shout at the devil is a pretty awesome record, but the rest of their output is pretty hit and miss, pretty much a singles band, stuff like Girls, Girls, Girls, Kickstart My Heart, Wild Side are cockrock anthems, but those albums suck as a whole
ac/dc: great band, see them live last october and they were still great live, too many good songs to list, also quite a bit of crap, but the good outweighs the bad, and when you buy an ac/dc record, you know exactly know what to expect, probably the most consistent band around, also deserve props because they were able to move on after losing bon scott while still releasing a classic album in back in black, and another good one in the razor's edge
led zeppelin: i have all their records, but i'm not a huge fan personally
gnr: appetite for destruction is probably the best cockrock/hair metal album, UYI I&II are pretty uneven
i think WASP is criminally underrated in the realm of 80s glam/cockrock/hair
iron maiden: pretty awesome band, the first two with paul dianno on lead vocals are very underrated, i recommend anyone check them out, because the material on them is just as good as the golden era stuff imo, albeit with more of a punk rock sound, golden era maiden NoTB, PoM, Powerslave, LaD, SiT, SSoaSS are all awesome metal albums, they kinda of went to crap after adrian smith left the band
