<edit>Took "sometimes I wanna call you, but I know you won't be there", as it was already translated at this link : http://www.cucumis.org/translation_3_t/view-the-translation_v_257555.html </edit> (03/08/francky thanks to sunnybebek's notification)
This part (requested by the same user) "sometimes I wanna call you, but I know you won't be there" has already been translated here:
http://www.cucumis.org/translation_3_t/view-the-translation_v_257555.html
So I think it would be better to edit the request and to keep only the first part "there's nothing I wouldn't do to hear your voice again".
