I cant change the names of my music files?

It comes up saying, if you change a file name extention, the file may become unusable. I have never had this problem before.

i get those, but mine comes with text files not mp3, i don' really bother i just change it's name but keep the extension as .txt, just change yours and keep it as .mp3
