i've looked at numerous track listings and keep seeing that there is a bonus track on the Reanimation disc. i remember getting this on release day and i never heard a bonus track. was there was a special edition that i am not aware of? and what is the bonus track? if it really does exist...
I believe that was Marilyn Manson's remix of By Myself. That was on certain editions. Also, I think there are a couple of live tracks on the iTunes download.
Buy Myself is a bonus track on the Japanese release of the album - Japanese releases of albums almost always have bonus tracks or some type of additional content, because it's actually cheaper in Japan to import a CD from the U.S. than it is to buy the domestic Japanese edition. And the iTunes edition also comes with that track, along with 2 live tracks that were previous single b-sides.
I know one of those live tracks is a live recording of "One Step Closer" with the "Reanimation" bridge (complete with Mike singing "Blood is pouring!") which was on the "Faint" 2 single.
