HDTV and Music

It seems that the preferred quality of video content goes up while preferred audio quality stays the same or goes down.

HD video has a portal to distribute high quality, high bandwidth, content. Music content is at the mercy of internet bandwidth.

A fundamental difference is the context. Video has many different levels of experience. HDTV, standard TV, web based HD and standard TV served by the networks, YouTube, and mobile video (iTunes).

Music has one level. iTunes and Amazon are about as premium an experience as you can get when it comes to making a purchase. iTunes is as good as it gets when listening to a library of music. Music social networks like hypem and last.fm are good but the quality isn't better (audio or experience quality).

Can we create different tiers and formats to experience music beyond what we have now? Can we create a 'high definition' experience?
