I need help with these two lyrics.

First one is the one that goes, "Follow me. Follow me" It's a dance song that can be heard on 94.5 WPST. There is a woman and a rapper singing this song.

The second one goes, "Everybody la la la la la. Everybody la la la la la. Oh No. Oh No. Oh No. Oh No, La la la." I heard it when I was at Dorney Park and Wildwater Kingdom in summer of 2001 with the YMCA Teen Camp.

Can anybody tell me what are the names of the songs and who sings them?
