Listened to my friend's copy yesterday. Gotta say, pretty damned weak on the whole. I like What I've done but it sounds so much like their previous soulfull creations (namely In the End, my favorite LP song).
But now it sounds like they want to change their format/style and with songs like Bleed it Out, if I remember it correctly (track 2, correct me if I am wrong) it seems like they want to be metal, but they just aren't any good at it. And as far as "back in the day", it's hard to think that way when this is only their third original album (no Collision Course or live albums included since it wasn't original music), and it went Hybrid Theory > Meteora > Minutes to Midnight. When I actually considered how little they've done, and how long it took to get these three together, my opinion of LP dropped when I went through Minutes. Not gonna buy it, might burn What I've Done onto a composite disc of favs (like I sound, sounds a bit like earlier songs of the same type, but is still appreciated), I can leave most, if not all, of the rest.
So RIP LP, I am done with thee, sorry.
