Who is singing

[ScottBakula]

I posted this in geeky stuff yesterday but have got no replies yet so I am hoping you music lovers can help .

Is there a app out there that can tell me who is singing a song.
I know there are loads that will tell me which band / artists is singing but I want one that can tell who is singing each word / line

So if I used if for say the Beatles it would tell me when Paul is singing , then when John singing .
Ideally it would bring up the words too.

Perhaps a bit like karaoke, a different colour for each singer and one for when they are in harmony..

Does such a app exist ?

About the time I was about to be demobbed from the Army, I became aware of a very distinctive voice that was often played on Radio 3.
It took over a year before I finally identified it as Emma Kirkby!

I think with bads or solo artist Google or some such can tell you who is singing, but my issue is I have been listening to music live recordings and studio and tho it's the same band it's sung by a different band member ( or duo ) or one will ding one line the other will sing the next line but that varies between live and studio recordings.

It's really frustrating when you don't know isn't it .
