Pip Radish said"If you can suggest how else I could have heard these tracks I'll be more sympathetic to your position, which I take to be that I shouldn't download anything ever."

What I suggest is that someone should not UPLOAD full albums without permission from whoever owns the rights. Once they are uploaded, I'm not surprised that MANY download them. It may be that whoever own those rights may be planning to re-issue it as a CD. Why bother to buy that CD if they already have it? (and, why is it necessary that you hear those tracks right now?)

All I can do is hope that YOU would buy it if it became available. Since the technology exists to easily copy and upload albums, we are getting into a VERY murky situation about the economics of music production.
What I DO think is that the owners of rights to older stuff, like LPs, should either make them freely available and creat a database where the public could look to KNOW what is permitted, or make it very clear that they do NOT wish certain properties to be copied. This won't stop piracy, but it would avoid a lot of gray areas.

Sometime soon, someone had better deal with the issue.
