Audio files are like a food recipe. If you bake a cake, and then try to get all the egg out after it's cooked, it's not going to work.
If you can find an instrumental (song without vocals) track and an acapella (vocals only) track, you can play the two together while still having them as two seperate files. Or if you personally know the person who produced the recording, they could make an instrumental and acapella for you. But you can't just get an .mp3 with vocals and instrumental and try to separate the two, without both ending up as a horrible mess.
