Congratulations in changing your question so many times that it no longer resembles the original...
You're right, I do download the odd track on eBay (usually the first 60s seconds) to remind me of what they sound like, so i can buy them for my own collection in future.
Not sure of the relevence of the "after a quick buck or two" part of your question though?
Anyway here's a tune that sprung to mind when reading your ramble, hope you like it...
