Every indication is that Miami Vice will be released with the music intact, so what's the problem? As for Quantum Leap, I simply didn't read the blurbs. Easy enough solution there.
Universal does the text thing on every release I've seen, which includes the A-Team and Magnum p.i. in addition to Quantum Leap. So, be aware if you buy either of those shows.
The thing I don't like about the Universal sets is the forced episode promo before every episode. Don't get me wrong; I'm glad this material is included. But, I find the segments give too much away, and I'd rather they be accessible from the menu.
