First question - will the songs and the extra content have DRM on them? If so, then it won't make it worth buying, no matter what "added value" you think you've put into it.
Second question - who would sit around with their friends looking at album art on a monitor? It was one thing when you could pass the album cover from person to person, read the notes and lyrics, pull the sleeves and look at the art on them. Now we would have to huddle arounf the computer, no hands on. It still lacks the tactile aspect. Interactive it may be, but only for the one holding the mouse.
Third question - does this mean you're going to improve the music quality on the albums? Can we expect more than one good track now? (Okay, I know that's two, but they really adress the same concept.)
Fourth question - why am I wasting my time on these questions? ;^)
