Pearl Jam -
Not For You Doesn't really get any easier than this as a simple Echord fingering based "riff" for almost the whole song.
Ramones -
I Wanna Be Your Boyfriend Only A Modicum Harder Than Not For You.

Pixies -
Giganticgood little "solo" to get you appregiating notes (on 2 strings only), and nothing but power chords otherwise.
Jane's -
Jane Says Watch this guy's lesson. The tabs all suck for this. it's easy as pie, and shows you how to "mix" between chords and scales while only requiring you to know and fret 2 very easy chords (G and A). [I happen to think this guy is wrong about the chorus though. Try just fretting a normal G chord, then lift your ring finger off of D with your pointer already placed on the C#, lift it off to B, then back to C# on the b string.]
Creedence -
Up Around The Bend Not really a "beginners" song, but its one to "grow into". If all you ever try is songs that are easy to play, you'll never learn nothin new. It will help you learn how to finger efficiently, that little solo is a good way to learn fingering and bends, and the intro riff is probably something you can start off playing. The chorus is a good little chord progression (G-D-A) to learn. Don't forget to start hammering that F# off and on at the D string when you are hitting the A in the chorus ... a little blues line, most tabs leave it out for some reason.
Zeppelin -
Over The Hills & Far AwayReally not *nearly* as hard as you think to play the main lick, and a song *every* guitarist should learn ASAP.
Mad Season -
River of Deceit Again, not nearly as hard as you would think, but challenging enough to give a beginner something to practice for a while, I would think. Also not boring as shit (like not for you). Have fun with it.
