It's a song I heard a couple years ago on a now-defunct alternative radio station. It's not "The Spider and the Fly" by the Stones, and it's not "The Spider and the Fly" by London After Midnight.
The band almost has a "Muse" type sound to them--it was on the alternative station. I've done every lyric search using every phrase I can think of, and my only recourse was to ask some people in a forum if they have any idea what this song could be.
My memory is horrible: it might not even mention a spider, but I'm fairly sure the song mentions a fly. I know: this is really crappy and incomplete information, but it's all I have! I really hope someone can help me, because I loved the song the minute I heard it and would love to buy the CD.
EDIT: I found the song I was looking for. Thanks for all the help! :-)
