true ... you can't ...
What you can do is to get rid of the most dominating frequences from the instruments, and perhaps boost a little the vocals (mostly they're arround 1500hz).
And if your track is filled full with other sounds (I really mean full) you can overlap it and have a small chance that the result is not SO bad.
But except that there is not much to do ...
*edit: Owyeah I allmost forgot, try to sync the instruments (percussion if it's in there) that have their rhythms with your track...
And Good luck ... http://trishula-records.com/artists-pages/melorix.html |

"While the automatic approach is easier, the manual approach can be accomplished in most audio editing software. It also provides insight into how the automatic vocal removal feature in most software works.
This method of removing vocals can be accomplished fairly easily, but depends greatly on how the entire mix was recorded. This method works when all or most of the non-vocal audio is mixed in stereo (some more to the left and some to the right) and the vocals are mixed in the center. Fortunately, this is common practice in popular music, making it a fairly reasonable method for many songs.
Tip: While most audio editors don't have an automatic vocal removal feature, many do provide "macro" functionality, which allows you to record the steps described above, and then replay them on any audio file or selection. See your program's documentation to learn how.
1. Open the stereo audio file in an audio editor.
2. Select and reverse the phase of the left channel (also called Invert or Flip). This option is usually presented in the Edit menu.
3. Mix the both the left and right channels of the stereo file into a single-channel (mono) audio file. This option is also usually found in the Edit menu, but is sometimes accomplished by editing the file's format properties from the File menu (ie. Sound Forge).
4. Split the single-channel audio file back into a stereo file that has the newly mixed single-channel on both the left and right channels. This procedure is usually close to the one used to mix the channels.
5. Now reverse the phase of the left channel back again, the same way it was accomplished earlier.
The resulting stereo audio file should now contain the same mix with all center-mixed audio cancelled from the mix. Hopefully, the entire instrumental contents will still exist, while the vocals will be canceled, or at least much more quite. "
This would make the instruments only file.. To extract the vocals:
" Well, some of you have asked if you can also do the opposite. That is to remove the backing tracks and just be left with the lead vocal part. The answer again is yes and no.
Yes, you can extract the lead vocal from a prerecorded song, but only if the vocal is panned directly in the center of the stereo field. But as with eliminating the lead vocal, the process isn't perfect. There isn't currently any audio software on the market that can analyze and extract only a single part from a recording. Instead, you have to isolate the material in the middle of the stereo field. That means isolating the vocal and everything else centered in the mix.
Fortunately, Sound Forge has a special Mid-Side conversion feature (normally used for another purpose) that pretty much makes this process automatic. Without it, the process would be much more involved (ie. having to remove the vocal first, converting to mono, phase inverting, and recombining with a mono version of the original file).
Here's how to do it the easy way in Sound Forge 4.5 and 5.0:
1) Open the original audio file.
2) Choose Edit>Select All to select all the data in the file.
3) Choose Process>Pan/Expand.
4) In the Pan/Expand dialog box, choose the Normal Mix Of MS Recording preset.
5) Click OK.
6) Choose Edit>Selection>Set.
7) Choose Left in the Channel parameter drop-down list.
8) Click OK.
9) Choose Edit>Copy.
10) Choose Edit>Paste Special>Paste To New.
11) Save your new audio file.
Depending on the type of material that you're processing, the results will vary, but they'll never be perfect. Anything that was in the middle of the mix will now be in your new audio file, which probably includes the vocal, bass, and some of the other background instruments. You can try to tweak the mix a bit with EQ, but other than that, what you get is what you get. Maybe in the future we'll have more sophisticated software available that will be able to analyze and separate specific sounds from an audio mix. " |

If they would put it like a (I'm making something to compare, Yes I am) .pdf or a .psd on a cd perhaps for music 
Every sample seperated on the cd ...
