Sorry Johnny, I don't think I explained myself very well earlier...
What I meant was that any live show you attend, the mix is not going to be the same for all monitors for the crowd and the mixing engineer(s) can decide to change this on the fly, sending different instruments/mic output signals to different monitors. With this in mind, live music (not recorded live music) is multichannel, in a sense...
I agree that songs with sound effects have greater impact in multichannel formats, but I have quite a few DVD-As and SACDs that are well mixed and are quite appropriate for multichannel use. Some of these are:
Donald Fagen - The Nightfly
Jeff Beck - Blow By Blow
The Allman Brothers Band - Live At The Fillmore East
Steely Dan - Two Against Nature
Pink Floyd - Dark Side Of The Moon
Grover Washington, Jr.- Winelight
Other thank DSOTM, I don't believe any of these have sound effects, yet all are well engineered and have great instrument placement for each of the channels. I suppose what genre of music is mixed in a multichannel format is highly subjective and debatable, but I've been pleased w/about 80% of my multichannel purchases to this point. Not all music can substancially benefit from multichannel mixes, but quite a few of them shine in this format.
I am aware of Michael Buble and while he does have a great voice, he's most definitely not my cup of tea. As for Canadian bands, I would give my left arm to hear some of Rush's material released in multichannel format. Something from Our Lady Peace, Triumph, Bruce Cockburn wouldn't be too bad, either.
I certainly can't disagree with you that $40 for an album released 30+years ago and is readily available (e.g., not an EU import, limited release, etc.) on other formats is way too much, it absolutely is. I'd like to buy the Amadeus soundtrack on SACD, but this also runs $40 and is only a two channel mix, so that ain't happenin' in my lifetime.
Strange that you mentioned L.A. Woman is a poor multichannel mix and that the Police's Greatest hits is pretty good. I've heard just the opposite about both, love both of these bands and think L.A. Woman is actually a well engineered mix. The fact that BTO and Foreigner have poor MC offerings doesn't necessarily mean all artists of a particular genre (Classic Rock, Alternative Rock, etc.) shouldn't be offered. If they came out with a few Led Zeppelin albums in MC format, I couldn't get it fast enough. Same goes for The Who (besides 'Tommy', which is already available), Rolling Stones, Supertramp, Heart, Elvis Costello and a few others... -TD
