Hmm, I'm pretty limited on this sort of stuff, but anyway...
Rival Schools - anything off their United By Fate CD... but some standout tracks are:
Travel By Telephone
Good Things
Used For Glue
Holding Sand
Undercovers On
Far - again, pretty much anything off their CD Water and Solutions. Standout tracks again...
Bury White
Mother Mary
The System
Wear It So Well
Water and Solutions
New End Original - same singer as Far, but slightly different. Only got one album, called "Thriller". Again, tracks...
14-41
Halo
Hostage
Lukewarm
Titanic
Basically anytime I've recommended these 3 before, I've been completely ignored, so feel free to do the same.
