Easy to test: toggle bit 16 in the first frame header, e.g. if the first 32
bits reads
31 0

ff fb 50 04 (crc off)
change it to
ff fa 50 04 (crc on)
Yes, the "CRC" will be invalid (65535 / 65536 of the time) but it's an
invalid MP3 frame anyway, so that should be okay. I only have Winamp to hand
here, but Nitrane 2.25 and Shibatch in_mpg123 1.18 don't seem to have any
trouble with it. mpg123 itself would be the acid test, though...
