I spend a fair amount of time combing through ebay auctions. Most of the time the records are out of my price range, but it's fun to see what's selling and for how much. Occasionally the seller posts audio and I usually do my best to download it somehow. It took me a while to learn how to do this, since there is no "click to download" button. The seller doesn't want to give anything away for free, of course. I think some have caught on to my game, and have begun to post only :30 second sample clips. When I do see the entire song has been posted, I rip it and add it to my iTunes library. I am not the first to do this, since someone else posted a collection of about 300 tracks on Rockhall forum last year. They culled the audio from Youtube and ebay, but I have a problem with posting audio from youtube vids here, because I feel it is replicating (stealing?) the work of others. I don't feel that way about ebay 45s, since I don't care if the seller gets mad at me. They probably don't even notice since once the record is sold they are done with it.
So here is the first batch of audio files that I personally ripped and archived. There are about 70 tracks in all, from auctions of June-August this year. It's mostly country, with some teeners and rockers thrown in.
I didn't plan to do a posting like this, so didn't save the label scan images separately. They should show up in your iTunes though, once you import the tracks.
I couldn't fit all the tracks into one download, because I don't have a premium Mediafire account.
