OTOH - who needs a permanent record anyway? All culture is flux & flow; things come, things go & we could do without the accumulated clutter and people getting too much bogged down in the past. I believe, with good reason, that Popular Musical Culture is an Unbroken Tradition of some 50,000 summers duration, and counting. For sure, there will be cherished residue, but let's keep it in perspective. All things have their time; all things must pass; but the Tradition of Living Human Music will endure as long as there are Living Humans to do it (and others to sneer at the for not doing it right).

The answer to digital corruption is simple though: if you treasure it, back it up!
