You don't need to sign the whole .ogg file itself - run it through a MD5
or/and SHA1 program and sign a message mentioning them instead. For
example:

Norway, 2001-10-15 19:52+0200

I hereby declare that the song "foo at the bar" is written and
copyrighted by me. Released under the GNU Music Licence (or
anything similar).

File name: foo_at_the_bar.ogg
File size: 12.345.678 bytes
MD5: 6bc7129b8e11a62d007858f3b2852554
SHA1: fdac34e9a835bdb8176077111d80ad838ab3

Øyvind and the Bluesbreakers

Feed this to the stamper service and you'll be OK.

Mvh
Øyvind
