[Possible OT] Wierd effects with CD player

Try this:
Get a CD walkman (or equivalent CD playing device with headphone socket,
and turn off G-protection or equivalent)
Put a CD in (an ORIGINAL CD, or one burnt from a lossless source [NOT
MP3]).
Play the CD, wait for the vocals to start.
Pull the headphones cord out by about 1mm or less (you will probably have
to hold it there, it will want to pop out or back in).
On SOME CDs, the vocals will completely vanish.
On others they wont, but other parts, eg guitar, drums, may.
I quickly tried a few CDs:
Where the vocals disappeared:
Metallica - Kill 'em all
Guns 'n roses - Greatest hits (some songs only, eg Sweet child o' mine and
Patience). Note that with these 2 songs it seems they have applied a slight
echo or reverb effect to the vocals and that is all you can hear of them.
Where it had little effect:
Megadeth - Rust in peace
Pantera - Cowboys from hell - Some interesting things happened with the
drums though.

I also tried listening to a version of Sweet child o' mine burnt from MP3
and heard a wavery metallic effect (sort of like the old WMAs used to sound
all the time )

My theory is that the vocals are mixed across both channels, with a slight
delay on one track and they somehow cancel each other out?

Or the vocals are only on one channel and pulling it out slightly
disconnects one?

Cheers,
