Ranked in order of "similar-itis":
95% UAGM - LNF: The most obvious one, with even the first verse riff and guitar solo being incredibly similar
85% MET - OC: very structurally similar; the intros and concluding crescendos of the instrumental sections especially
80% PMU - OTBOA: very similar structure
70% LTL - BAL: pretty similar up thru the bridge but then it falls apart (both have a major-key uplifting sound as pretty much all of I&W does)
60% WFS - FFH: mostly similar only due to being piano-based and their relation to the ensuing songs
50% AD - TITL: TITL is actually more similar to TSCO than AD in my opinion
TTT and Surrounded really bear no resemblance to any song on ADTOE. BAI doesn't seem to be mentioned much, but really that first verse bass-and-drum pattern IS a direct rip-off of LTL; it's even in the same time sig isn't it?
By the way I love ADTOE, so I have no problem with the "homage".
