Tobias, not only do I think it's on topic, I also feel it could be taken a step further.

FJ has posted some vocal only video/audios of the actual recordings. There are MANY of these. It might be really useful to use those as additional reference track.

BTW, they have them for many instruments as well.

Great thread.
