The Plan 9 CD-ROM needed about 100MB for the full distribution, if that. We hatched a plan to fill up the rest with encoded music and include the software to decode it. (We wanted to get the encoder out too, but lawyers stood in the way. Keep reading.) Using connections I had with folks in the area, and some very helpful friends in the music business, I got permission to distribute several hours of existing recorded stuff from groups like the Residents and Wire. Lou Reed gave a couple of pieces too - he was very interested in Ken and Sean's work (which, it should be noted, was built on groundbreaking work done in the acoustics center at Bell Labs) and visited us to check it out. Debby Harry even recorded an original song for us in the studio.
We had permission for all this of course, and releases from everyone involved. It was very exciting.
So naturally, just before release, an asshole (I am being kind) lawyer at AT&T headquarters in Manhattan stopped the project cold. In a phone call that treated me as shabbily as I have ever been, he said he didn't know who these "assholes" (again, but this time his term) were and therefore the releases were meaningless because anyone could have written them.
And that, my friends, is why MP-3 took off instead of the far better follow-on system we were on the cusp of getting out the door.
P.S. No, I don't have the music any more. Too sad to keep.
