Who is the "we" that is in trouble? Us as music fans? The music creators? Society in general?
As music fans, we'll never have to worry about running out of awesome new music to listen to. The inexorable advance of technology that lowered the prices for consumers also greatly lowered the prices for creators, thus hugely expanding their numbers. And if less money floating around decreases the motivation of some musicians, that's probably better for listeners, as I'd rather hear music motivated by passion than money anyway.
For the music creators, yes, there is less money going around than there used to be, but really, that 40-year period where artists could make a buttload selling recorded copies of their music was a historical anomaly.
I feel like society still values music just as much as they used to, as the live-music industry has continued to do quite well. But technology is just making album-ownership a thing of the past.
The $120/year I spend on recorded music, while a lot less than I spent 15 years ago, is still twice what the average music consumer has spent throughout history (and a MUCH higher percentage of it goes to artists/labels rather than middlemen). I don't think that's really "sad", it's just the nature of things. It's as sad as the fact that consumers today spend a lot less stamps and stationary than they did 20 years ago. Things change, and none of us signed a contract to continue spending a set yearly amount on recorded music in perpetuity.
