Wedding is in a couple of weeks and I can't think of songs for the entrances!!?

I need help with picking songs for the bridal party entrance and our entrance as well as the cake cutting and garter toss. We want something really upbeat and fast paced to livin' up the crowd but I can't seem to come up with anything and the wedding is coming up real soon!!!!! Please send me your ideas, I could use all the songs you can think of. Thanks alot and wish me luck!
