I have no idea when did this song come out and who sings on it, or who produced it, I don't really know anything about it but the main melody/rhythm. So I tried to mimic the song with FL Studio and uploaded the sample to picosong. You don't need to download it because the site has an embedded MP3 player. I really would like to know the song name because I like the song much and I always go crazy when I hear it on the radio, but I never got the name. In the song, there is both a male voice and female voice singing. The lead sound on the sample is the vocals and the piano is the main melody/chord progression.
