CD sales shouldn't come back up because...
1) CD sales dropped because of a bad economy
2) The RIAA and it's constituants put out less CD's than previous years, explaining further for the drop in CD sales
3) You're comparing with the CD sales of the last 5 years, which were record breaking years for the industry....why do people expect sales of CDs to never stop rising?
This price drop shows the industry can "afford" to sell CD's cheaper. If they would balance where the money goes, they could create cheaper CD's. Currently the artist/band is getting ripped off, the consumer is paying too much for too little music, and the companies spend their cash fruitlessly and take it out on the consumer and artists.
When I only get 12 songs on a CD when I know that the band/artist created at least 15 songs in the studio I feel cheated. There is this golden rule in the industry that 12 songs is enough to keep the consumer happy while cutting costs on mastering the songs. And not all songs on the latest CD were created for that CD. You could be listening to a track that was recorded 5 years ago for another CD but didn't "make the cut" for the final 12 songs, so it ends up in a later CD.
The music industry has been selling me images of the artists and not the music. They put me in a sales demographic because they need to sell as much as they can. If they stop spending money on market analysis and TV advertisments, as well as these 500,000 dollar music videos MAYBE, just MAYBE they might be able to give me more music for a cheaper price, while they still can go home in their Maserati's and Jaguar's. They sell me the image before the music...so the music becomes worthless. So why not grab the music for free then?
