got an mp3 via email from a musician friend of mine today. when i try to open it (in any app… itunes, quicktime, vlc, etc), i get this message as if it's a new Application that i just downloaded from the internet.
i KNOW what to do if it's an app (keep my system prefs security settings & secondary-click on it & choose open that way) that i trust, but i've never experienced this happening before with "Files" that i trust.
is this normal & safe to open as if it was an app? or could something have happened to it & opening could be bad? or could it have been intercepted & actually be some sort of trojan or something?

I have two guesses:
By the way, mp3 files must be able to play back by just quick previewing them (Space bar).
