Glad to see you in the forum, but even better to see someone willing to pursue high quality next-generation audio production as an alternative to the miserable iPod "low-fi" madness. If only the major music labels could pull their heads out of their backsides on this thing.
Blu-ray can make next-generation audio standards a reality in millions of homes where DVD-A and SACD could not. The disc format is far superior in data capacity to DVD. Blu-ray players are multiple purpose devices (especially the PS3). DVD-A and SACD were merely single purpose players. The main attraction for Blu-ray is HD-quality movies, and that's going to sell many millions of players. As the install base of players grows into the tens of millions a very big potential market for high definition music will emerge.

Technically, a music producer can get away with supporting only one format. Any Blu-ray player at least has to offer built-in decoding for lossy Dolby Digital and DTS and be able to output either in 2-channel form. This is why many BDs from Fox and New Line have DTS-HD as the only audio format on the disc. Almost anyone with an existing 5.1 surround setup will at least be able to play lossy DTS and Dolby Digital, unless his receiver is a model over 10 years old (and possibly a cheap one at that).
Of course the support for both Dolby TrueHD and DTS-HD is a little spotty within various 1st generation Blu-ray players and a few 2nd generation players too. Support of both DTS-HD and Dolby TrueHD is much better within new audio-video receivers and surround controllers. Lack of DTS-HD support will be a temporary thing, just as equipment lacking DTS support began to disappear in the late 1990s.
It would be less expensive in terms of licensing costs for a music producer to choose either Dolby TrueHD or DTS-HD Master Audio exclusively. By supporting only one of the two lossless formats less disc space would be used, making it easier to fit the project on a BD-25 instead of using a more expensive BD-50.
I think the greater priority in a high resolution music product is supporting multiple audio mix-downs. Any high resolution music release on Blu-ray should feature the mix in 2.0 channel stereo and 5.1 (or 7.1) surround. If the disc capacity can support 2.0 and 5.1/7.1 mixes in both Dolby TrueHD and DTS-HD Master Audio -and leave enough space for on screen video/graphics content and other extras then that would be great.
