Depends on how you look at it.
The distribution systems are better today. So more recorded music might be available for sale now than at any time since the beginning of recorded music.
Tomorrow, looks like the distribution systems will even be better. It's more likely that MORE music will be available to MORE people in the future. Satelite, cable, and the internet radio are offering more music thru the air than before.
People hear music thru their cell phones. They buy ringtones. More music is played on TV shows and there are more shows and movies created than in the past. More music is being used (and paid for). Do TV shows and movies use music without paying for it?? Alot of new artists get their songs played on commercials, so they have other forms of revenue coming to them, not just the sales of CDs.
Looks like music availability is going UP.
Just the distribution systems are changing. Artists can make money selling CDs, selling online, playing concerts, doing commercials, putting their songs on TV or movies, doing exclusives for radio, etc. More distribution systems, more money.
There is still a BIG market for MUSIC.
Since I seem to have lost the ability to communicate clearly I'll go away. Have nice futures.
