OK i admit they mostly play what you wanna hear (as with all good old bands) but its still a nice touch, an y'know atleast it means we have the choice if enough people vote for random songs it may make for a different setlist plus it gives the band feedback on what songs people wanna hear live! They may see a couple of songs they've not played in ages are highly requested an they can throw them in to future setlists if not WOA
Also true to choose between classics, not so mucha problem for me as I'm not a massive fan, I just want wheels of steel an heavy metal thunder! I would prefer denim and leather out of the 2 you named though.
