Hint: To appreciate this, you need to think of the answer in terms of only the TITLE, not the whole song. Think of what the title says; no need to reflect on the actual song that it's referring to. That's what I did when I answered it. :)
I couldn't pick just one band...so I ended up answering this *8 times*! Each time I had a different band in mind. Whew!
So I'll just post the semi-sikat, semi-mainstream bands that most people know about...even though I don't listen to most of them anymore.

I choose Dashboard Confessional...just for convenience.
