Cut the page, move any relevant examples to Too Good To Last.

Mark it as an Audience Reaction, declutter the definition to make it clear that "in the case of Lostalgia, the core issue is that for technical/practical reasons, the original works cannot be experienced again. (May overlap with Keep Circulating the Tapes)"

For example:

• Lostalgia: before Bob And Alice broke through with their first record, they performed at local clubs where they covered famous songs. Once they broke through they never recorded a cover, so you'll never be able to hear Bob and Alice sing their version of "Yesterday".
