Program that can break apart music??
 

What I'm basically asking is, well, is there any program that can break apart a song (i.e. separate the vocals from the guitars, isolate a specific rhythm on drums and have no bass interjections, etc. etc.). I think it might be helpful for me, since I'm new to remixing and such (it seems like a very interesting hobby to get into. ^^

Any tips or helpful links would be appreciated. Thanks!
