several songs to identify, please

Hi, can you help me to identify several songs, please?

1) The song with a refrain at the end:

I don't need her, I don't want her

2) Songs with the following lines:

"night and day I was waiting for you to come"
"...to be my lover, wake me up, can't believe...."
"it seems to me you're so beautiful"

3) Some rap song with "we don't care" refrain

What I was able to hear in the song:

"I am proud of the fact... keep united", "up in the club"

4) Songs with the following lines:

"The girl's on journey for first time, her name was Sara"
"Sarah's waiting for a man"
"she will get into your mind"

Thank you!

Kanye West had a song on his first album called "we don't care"

A band called Shampoo also has a song called "We Don't Care," as do the Audio Bullys.

Thanks, but unfortunately these are not the song I searched

maybe someone will be able to help me now. Thanks!
