i saw it on " The Drop " on Sitv
It think its by don abusivo but there was another guy singing on the song and the corous went somthing like

una vida feliz
..........somthing somthing somthin........
Solo tu y yo ,
Solo tu y yo

and around the end of the song the rapper was like llevante el telefono y llama me
thats all i kno
plz help it was a really beautiful song- the rhythm was like a r&b meets west coast rap thing.
