The Sugababes - Overload
Art Brut - Formed a Band
Suede - The Drowners
MIA - Galang
Arguable (i.e. on some days these are my favorite songs by these artists):
The New Pornographers - Letter from an Occupant
Katy B - Katy on a Mission (although she had feature credits before that)
Uncle Tupelo - Graveyard Shift
The Cars - Just What I Needed
The Young Rascals - I Ain't Gonna Eat Out My Heart Anymore
The Decemberists - Leslie Anne Levine
Lana Del Rey - Video Games (if you don't count the Lizzy Grant stuff)
I disagree with you on Ramones (certainly regarding the parenthetical - just because their songs had similar instrumentation, arrangements and tempos doesn't mean they were rewrites of each other). Petty and Prefab are fine nominations - I probably disagree, but I'd put those songs among their top 5 or 10. Agreed on Only Ones and Boston.
I disagree with you on Moody Blues, as do most people here I imagine (even though "Go Now" is a decent song).
