Need help identifying 2 songs, with clips

Found these clips in some random videos, cannot make out enough lyrics to do a proper search.
Clip 1 and Clip 3 are of the same song, slightly different chunks:
Clip 1:

Clip3:
http://rapidshare.de/files/22388428/clip3.mp3.html

Clip 4 is another song, especially would like to know who the female vocalist is:
Clip 4:

Each clip is under 500k.

If you haven't used rapidshare before, scroll down to the 'free' button then enter the image code to download.

Thanks for any help.
