i need help with searching this
 

I need to know the name of a song that begins with a piano and a woman singing and then in the first chorus it begins playing a electric guitar and other rock oriented instruments. After the second chorus it only plays piano and few lyrics for a little moment and then it goes rock again. At the final it begins playing choirs. I hope this information is enough to help. Thank you

This information is absolutely not enough.
Where and when did you hear it? What genre was is specifically? How did the voice and the instruments sound? What language was it? Etc...
It'd be impossible to guess by the information you are giving here.

Well i remember that the last word of the first 2 chorus were yeah and that that the begining of the 3 chorus was hulelei. If i remember more detail i will let you know.

"Set you free" - n-trance?

No is not. The song i am looking for uses a electric guitar, this one uses more tecno sound but thanks for your effort anyways
