help with my music

[Jamezcua]

I downloaded 2 music files from mediafire and they show up in the downloads section of the browser but they just says .bin, but when I click on it the song plays fine. But and I go to the music app it shows that I have no music in my phone. Were can those files be? I already tried using sdrescan and it did not work. Does anyone have a solution to this? Or way am i doing wrong?
