I'm really into (what I call) the "Green Day" knock off bands. Basically it's that punk/fun rock stuff. Here are some of my favotites (to give you a better idea of what I'm looking for):
A New Found Glory - Dressed To Kill
A New Found Glory - Boy Crazy
Andrew W.K. - We Want Fun
Blink 182 - All the Small Things
Bowling for Soup - Ohio (Come Back To Texas)
Bowling for Soup - Life After Lisa
Bowling For Soup - Down For The Count
Butch Walker - My Way
Fountains of Wayne - Stacy's Mom
Good Charlotte - Lifestyles Of The Rich And Famous
Good Charlotte - Girls & Boys
Good Charlotte - Riot Girl
Good Charlotte - The Day That I Die
Riddlin' Kids - I Feel Fine
Simple Plan - (Every song)
SR71 - Kick Me When I'm High
Sugarcult - Memory
Sugarcult - How Does It Feel
Zebrahead - Playmate Of The Year
Hopefully that's a good sampling to give you an idea of what I'm looking for. I guess "Bowling for Soup" is the best band to compare this fun/punk stuff to.
Can anyone suggest bands (that aren't well known) that fit this category? They have to be heavy, but not really heavy. They need that melodic/fun/alternative sort of edge to them.
