Break up songs always depend upon whether you are the dumper or the dumpee. For the dumper, I like:
"You're Moving Out Today" - Carole Bayer-Sager
"Life Goes On" - LeAnn Rimes
"Sober" - Jennifer Paige
"You Sh!t Me To Tears" - The Tenants
"Don't Shed A Tear" - Paul Carrack
If you are the one getting dumped, it's a very different kettle of fish.
"Crucify" - Tori Amos rings true for me, as does "The Flame" - Cheap Trick (shows my age, huh?).
There are so many I've always liked, but I haven't been on either side of the dumped line for a little while now.
