Neil Young likes a quality product and he hates waste.

So, when a "mastering error" screwed up the sound on his 1978 album, Comes a Time, Young wanted to recall the album.  However, 200,000 copies had already been shipped around the world.

Neil Young bought all of them.

He recently explained that move to Rolling Stone:

"That was because it was a mastering error. The tape got damaged when it went through the airport or something. I had to go back and use a copy of the master — it was a copy, but it had better-sounding playback than the other one."

What did he do with 200,000 copies of his own album?  "I made a barn roof out of them. I used them as shingles."
