Can I somehow download music that is already a .dcf file?

I have just gotten a new phone for my birthday and i wanted to put some new songs on it but when i went to download the songs andput them on i only got the intro of the song because they were mp3. I need .dcf music but i dont want to download the software because it takes to long and i cant figure it out. Is there any sites that i can download .dcf music and not mp3 music?
