On the Batman soundtrack , Prince has given the Sounds Of Blackness credit for choir vocals.As many times as I listened to that album & cd, I never noticed any choir in any of the songs.Was that just a shout out,was the mike not on, or do I have to blast my speakers to hear them. Just something I always wanted to know.

One place they appear is on the track 'The Future'. Use headphones for a better listen. They don't sing words but a full choir is present in the background. The choir was sampled and played back on a midi keyboard and you'll hear them come in and out of the mix at various times.

Thank you. Will check it out.
