I don't think so. Most, if not all, are available through streaming services such such as Spotify, or can be listened to/bought on Bandcamp, itunes, Deezer, etc.I wonder if any of them contain content that is not available online, let alone available free of charge.
This is still true today. If one buys music, then logically they intend to listen to it, otherwise why would one bother?In the past, the main point of buying them was listening to the content on them.
For most people, this is indeed the case. That's why streaming services such as Spotify are so popular, and those who don't want to pay for the service can use YouTube, or some sites such as Bandcamp will let you listen without the obligation to buy.If most people can easily listen to all the content without buying copies, the takes away that reason to buy them.
Yet there is still a market for phyical copies. People still buy them and there are a number of reasons:
1) A physical copy engages more of the senses; you can see it, feel it, you have the artwork plus any posters, notes or inserts that might have been included. This is missing in a digital download. There's often much more to a release than just the music.
2) Collectors might want to collect rare records, as many releases as possible by one particular artist, or collect releases belonging to one genre. Usually, they want something tangible. There are some people on RYM who listen and rate as many albums as possible without buying them - I suppose that is a kind of collecting in a similar way to trainspotting being a kind of collecting, but I don't fall into this category. I like to own physical copies.
3) There are some people out there who just buy vinyl records because they think it's hip/trendy, they might not want to listen and might not even own a turntable. They might display the albums on the wall, or just have them without playing. I don't think this is common, though.
4) Some collect for the sake of collecting and don't listen to them, but leave them sealed in the expectation that they will one day become valuable. I'm not one of those. I listen to all of the records/CDs that I buy.
5) Some people want to support the artist by buying their music, whether that be in physical form or a download, just as some football supporters still go to the stadium to watch a game rather than watch it on TV.
