If you want a challenge, you can\'t beat the Grand scheme of things, or spunk. However, I would suggest Lit as a first song and see how far you get. Its a simple circus theme in 3/4 (oopm-pa-pa).
Additionally, if you really want to pick your brain, don\'t do tab, do sheet music for all four instruments. It will give you a much better idea of pb\'s rhythmic style to see how the instruments work against each other (especially adirens pollyrhythms), which are things that tab doesn\'t really convey. This is where lit is a great song. It always starts real loose, and it sounds like all the instruments are fighting each other; however on closer look you\'ll find the rhythm is actually holding them together in a weird sort of loose almost free time.
even if you can\'t figure out the full chords or exact notes, just try getting the rhythm slashes for each instrument in one part of one song and look at how it all fits together. A warning: its not all in 4/4 and there are tuplets (quintuplets and sextuplets sometimes). Tim especially likes using these in jams to spice up the rhythm.
It will also show you the bands chord structuring as a unit and give you a better understanding of how the melodies twist around each other. Theres alot of information in there, but if you can read sheet music, thats definetly the way to go. It will teach you dynamics and note length as well as what note to play. write me if you need to.
