Program to separate bass, vocals, and guitar from mp3 files

does anyone know of a program that can separate bass, guitar, drums, vocals, ect. from mp3 files into separate files so i can listen to them each individually?
ive searched, but i dont know what keywords to use, so im finding things that are completely irrelevant. Any links, search tips or anything helpful would be greatly appreciated.
Thanks.

is this even possible?

I don't know if this is possible, but I did a search myself and all I could find (up untill now) is are vocal removers. They allow you to remove the vocal on the song... It's something, no? Oh, note that they are not free (and I'm not using any of them so I do not know how good they are!)

Here are my findings:

1. 'YoGen Vocal Remover': "removes vocals from PCM WAV files so you can save the song, without vocals", but it's description also says: "some songs work great while others do not."

2. Karaoke CD+G Creator 2.0.1: Actually this allows you to create 'karaoke-songs', but can also be used to remove (or suppress) the vocals.

It's all I could find!
