I don't understand why you would give an entire season of a show on DVD a poor rating just because the music has changed! What about the writing and the acting and even the lighting? There must have been other aspects of this show that you enjoyed. I mean, it wasn't an opera!
I'm sure the DVD producers would have kept the music the same if they could have gotten the rights to the songs, but clearly the music industry has some issues. Why not write and complain to the companies and individuals that refused to give the rights to the songs that you liked so very very very very much to the DVD producers, instead of giving the entire DVD a poor rating based on something the DVD producers probably couldn't do anything about (short of not releasing the show at all)?
Personally, I didn't even notice that the music was different. Any song they used on this show originally has probably been played a million times by now. I mean, it's 2005, and they were written in the 1980's for heaven's sake! Sure they probably enhanced the show at the time, and it would have been nice to have everything the same as before, but they hardly make or break the entire production.
I'm really glad that they are putting all these old shows out on DVD. If you liked 21 Jump Street the first time around, for any reason besides the music, then you should be very happy with this set. It looks and sounds great, and it has wonderful commentary on one episode (see below). If you only liked it for the music, go buy some used CD's and QYB.
(Oh, and to the person who was upset about Peter DeLuise not giving an interview...he provides truely excellent commentary for an episode in both the first and the second season. He gives you all sorts of fun behind-the-scenes stuff, and he is neither bored nor boring, which is tons more than can be said for most people who do commentaries. Please, cool TV and movie people with nothing better to do than read lame reviews on Amazon, if you are going to do a commentary on a DVD, do your fans a favor and watch this guy's first!)
