Rhino put forth a good effort when they released this 25th anniversary version of the soundtrack to coincide with the release of the DVD... but it's not quite perfect.
I will say that this version of the soundtrack includes just about every song (including the outtake "Once In A While"), whereas the original version left out a few cuts.
I will also point out that Rhino added a lot of dialogue to this album. The tracks are led in by the dialogue that precedes it in the film, which can be annoying as some of them are quite L-O-N-G. I know Rhino had good intentions, but I wish they would have done it on separate tracks so you can skip over them if you like. It's not horrible though. You'll live.
So back to the actual songs. As every other reviewer points out, this version has the previously unavailable "Once In A While," as well as "Sword Of Damocles" and "Planet, Schmanet, Janet," which were left off of the original album. And also as noted, the latter two songs sound like they've been recorded right off the television-- with the film's sound effects & everything. I guess the masters are MIA or something. It also abruptly stops on "Planet, Schmanet, Janet" before the "You're a hot dog..." coda, which is a shame! I love that song's ending!
So I guess this anniversary soundtrack suffers from gluttony-- my complaints stem from the fact that there is too much included on here. The dialogue is unnecessary. And the few extra tracks, while I'm glad they're there, could have been mastered properly. As for the rest, it's the same as the original soundtrack (only without that unnecessary "Time Warp" remix). The overall sound quality (those 2 songs notwithstanding) is pretty similar to the original release, if not a tiny bit better. I didn't notice any huge difference. So this is just like the original version + more. No real need to complain. Nothing's missing. If anything, there's just TOO much here.
I will note that the booklet & album art are cool. Some great photos & linear notes.
You might as well go with this version over the original-- this has got everything the original has & then some-- unless you really can't stand hearing the dialogue. Plus this has a great booklet, something the previous release lacked. So I'll give Rhino an "A" for effort.
