Should Star Wars Episode 7 Soundtrack have good vocal musicians?

I'd wager that's a given. Any actual singing will probably like "Lapti Nek" and "Jedi Rocks".

 

I hope not, it just wouldn't be right.

 

This is what I want.

 

I hope that John Williams changes it up from the frequent use of orchestral vocal choir as he did in throughout the PT. Considering it's all but nonexistent in the OT, having a different type of feel altogether for the ST would be fantastic – meaning each trilogy would have it's own thematic musical element and feel for the score.

Perhaps they could use solo voices more, such as how they're utilized throughout the Lord of the rings soundtrack. (The best of which occurs in the two Towers.) I would quite enjoy hearing something like that...
