I think the reason Vinyl has survived at the level it has is not because of the niche audiophiles and vinylphiles that are apt to keep any old format going just 'cause...but rather it is because of the dance/hip hop crowd. Folks, the DJ has ruled over vinyl for the last 20 years because of the ease of manipulation, 12" and albums have lived on and on in high numbers. Without the DJ's, most kids would not be into it because vinyl would not be as "cool." Sure we would have the folks that want to listen to the original 60's and 70's acid rock on their bazaar tables but overall, the DJ's kept it en vogue to a point now that people my age and under are really interested in getting back into it. With the increase of indie artists pressing lp's, we have a choice between buying the CD or the LP.
Here is an AWESOME tactic by one record label: Merge, they release an LP and provide a link to the site to download the digital files in a high bitrate. How cool is that!!! If all LP's came with this option I bet LP's would fly off the shelves. Camera Obscura's recent album, noted to be among the best released this year, came out on Merge. I bought the LP and have the luxury of having the mp3s on my iPod for work. Perfect example of having one's cake and eating it to. All that is left is that the digifiles come lossless, then we REALLY have it all.
