Lost Amy Winehouse song

if one was to discover a song by elvis or a composition by Bach or a painting by a famous artist long dead it would be big news and worth a lot of money. An Amy Winehouse song newly discovered may be valuable now otherwise the discovery of the song mighht have been hidden for twenty or thirty years or maybe longer. Afterall, in ten or twenty years no one will know who she is or care that one of her unreleased songs had been discovered. Get it while the getting is good.
