It can be a single I suppose, but have you listened to a CD or something and passed out on a song because it didn't releate to you? You listen to an album, listen to a non-single and let it pass for a year or two, then suddenly something comes up and you releate to the song and now you suddenly, after so long, ***** the track and ask yourself...
"What was I thinking skipping this track?"
For instance, Jordin Sparks "Next to You."
I have heard this song probably 5 times MAX since 2007, since her debut release. I came across a video on Youtube of a movie that show cased this song to it and that's how I re-lived my passion for this song.
Now I have over 20 plays since yesterday and I am asking myself...."Why haven't I done this 3 years ago, when I could have heard it so much more."
(I got more, but I can't think of it right now...let me think)
