If you have heard a hipster refer to this song when discussing the bastardization of indie rock, you will likely see it on this list. These are cross over hits that explode from more obscure indie/alternative rock circles to the mainstream public. Some of them don't necessarily chart high, but have staying power and age well. A lot of them are even radio regulars to this day (providing a rare treat on normally excruciatingly bad radio stations). You may hear them in commercials, TV shows, movies, or even at the mall. You may hear your friend, who claims that Fall out Boy and Three Days Grace are his favorite bands, singing these songs. For better or for worse, these songs unexpectedly (and sometimes regrettably) became a part of pop culture. A rare intersection of good music with mainstream culture which provides proof for those of us that like to believe that the common man can (periodically) embrace good music.
