I am sure you are right about the magic. A single 45 had to be saved up for and was a thing to be cherished. Albums were even more so. A single mp3 track can be downloaded in seconds and it does seem to take something away. YouTube etc also allows you to listen to almost anything you want, whenever you want, so you don't have to wait or work to hear songs.
Is it just me, but I used to buy an album and play it to death, so I got to know them extremely well? These days, I'm on to the next thing and I admit that I know new material less well.
I think it's more than just changing how you go about listening Martin...when I was a kid I had about 30 albums, so you ended up playing them over and over memorizing every subtle nuance. As you get older and your collection grows, looking at this thread you can see we have some serious collectors in here....you simply can't make the time to really play everything as often as you did when you were starting out.
Like I said to Phantasmagoria, when you get 1000's of CD's to choose from it takes a while to decide what to play, I found that out decades ago.
There are some "special" albums I will always sneak into my rotation, the ones that have sentimental value to me, especially all the records I had as a kid. I've got almost all of them on vinyl again and love time tripping back to my youth, if only for a little while.
