I'm sure they probably can.  That's a bit different than DRM, though, 
which has the explicit stated goal of preventing people from 
"inappropriate use".  Watermarking allows them to act reactivley - and I 
believe is fairly easy to remove anyways...

mplayer -ao pcm:file=temp.wav file.mp3
lame -h temp.wav file-without-watermark.mp3

(Might have the parameters wrong, but I think you know what I mean).
