If you are ranting, then I guess I must be too

"Ranting" sounds unpleasant and I would probably consider it so if you were not engaging in an intelligent exchange.
On the "good music" thing, I understand there are ways that I might increase the odds of enjoying more tracks on an album but after all, we are talking about a highly subjective thing here. How a musical performance affects (or fails to do so) an individual is a very personal thing. I have found that asking the "opinion" of others, even those who know me, does not actually amount to much help in that regard. Besides, if I go and get everyone else's opinion on the music before I get it then by definition, I am only buying it if is
popular. Britney Spears!! Here we come!!!
On the price of "new" technology vs. established technology: You are right about the price of CDs not being "fixed" at $15. I remember paying around $17 for some of the first CDs I ever bought back in 1986 (I believe). I also know Best Buy has lots of them
today in the $12 range but a some places do still sell them in the $15 range. You are also right about the fact that all of the items you mentioned cost less now than when they were introduced. My point had more to do with the perceived drop in prices of movies (VHS/DVD) being FAR greater than the drop in music CD prices in spite of the fact that:
a) CDs have been around longer than DVDs.
b) As you point out, DVDs include additional materials and capabilities when compared to VHS.
c) The cost of producing/selling a music CD has dropped significantly over time due to technological advances.
I never said that a DVD and a CD
should be priced comparably but in any case, the number of "revenue streams" of DVD vs. CD made no difference in what I wrote. I purposely listed a sales figure of $800 - $1 billion for
box office AND DVD sales so we could make a straight out comparison with a chart topping music CD. I did that because of the very reason you stated: Lots of movies (and albums) lose money which the companies will try to recoup with the sales of popular items. Everything else you mention (dealing with artists/content creators, marketing, etc.) constitutes expenses that both industries incur.
The only thing that is different is the scale of the amount of revenues brought in by each of their products. That difference in scale also applies to the costs involved in the production of their products. Heck, a movie studio will routinely spend more just on marketing a single movie than a record company will spend producing a CD (how often do you see a prime time TV ad for a new music CD release?). Even if you focus only on DVD sales (no box office receipts), industry estimates I have seen indicate DVD sales can account for as much as 30% of the total revenue for a popular film. Does looking at $200 million (vs. $800 million total) in DVD sales alone change the argument here? I don't think so. Scale aside, the comparison is more than fair and if so, it is difficult to justify a CD costing almost as much as a DVD.
BTW: Look
here for a sampling of the top grossing movies to see that the "$800 mil. to $1 bil. box office and DVD sales" example for a blockbuster was not out of line. These figures are box office only, no DVD sales included.
