I used to work at Kmart and they had the in-store music system called the Kmart Radio Network. They played real songs (not elevator music) but some of the songs were pretty obscure. By writing down lyrics, I could usually Google it and find out the song's title and artist. Except this one:
It sounds like the group M2M to me, but I can't find this song in their catalog. The chorus sounds like the singer is saying, "Every day.....Every Night....I....I"
That's all I remember. Where I put "I....I" is where she is holding the note for a long time....and the note drops.
Not much to go on. Thanks.
