I'm trying to find a song from about 1995.  I believe it would have
been out about the same time as Collective Soul and Better Than Ezra
hit the charts and was the same genre as those two bands.  Pretty sure
the song was sung by a band and not an individual person.

Other than the time frame of the song in question, the only other
thing I remember about the song is an image of the guy singing looking
out the sidelight of his window (at the girl he'd broken up with,
maybe).

This is all terribly vague but here's hoping...

At a guess, you may be referring to a track called "Every Day Hurts"
which was originally released by Sad Cafe in the 80's - it may have
been re-issued as I think it had appeared in advertisements at that
time.

Good luck
