It's a pity that this song was released the following year after M2M's split in 2002. Considered to be the best song from the Norwegian Pop duo, this is a very sad song used to describe a painful aftermath of breakup in a romantic relationship or the loss of a loved one. The author was asking herself why she didn't cherish the relationship when the other was still around with her, and now that the significant other is gone, she is very sad, filled with regrets.
Although i never seen M2M perform this song live before due to the premature split before the song's release, i still hope the duo could at least somehow come back together for some events to perform.
Below is the chords sheet for M2M - The Day You Went Away.
