The song is one of the best songs I've heard from the genre of emo. For people that don't know emo is a rather new style of alternative, mixing both soft melodies with hard riffs, and compromising of both soft singing and ferocious screams. Thursday is a small group from N.J. Their sound is pretty original, well original in the sense that just about all emo bands are too small to be recognized. Both of Thursday's albums are excellent but if you want to get a taste of them check out This Side of Brightness.
"Understanding in a Car Crash" is the song that brought me to love Thursday, a hardcore emo rock band from the New Jersey area. Emo (for "emo"-tional) is a genre that encompasses deep and tenderly obscure lyrics with raw, impassioned screams and hard rock riffs. Thursday is probably the best emo band out there. This is a great song about wasted time and wanted love, so listen to it! You might discover an emo-punker inside of you that you never knew existed!
