Relient K is one of those bands that everyone knows a song by or you say "Oh i've heard this one before." My favorite from Relient K comes from Mmhmm.
Coming out a couple years ago, i don't think there is a bad song on this record. They also have put out a few awesome cover records and even a christmas record on top of it all. I like how most of it is pretty straight forward pop rock but at the same time there are slower songs like "Let it all out" a great breakup song.
Relient K - mmHmm - 09 - Let It All Out
If you've heard of Relient K before then i highly suggest you go and relisten to their stuff. If you haven't then go buy a record or two!
