Yes of course but I meant like known copies, cause one guy already has his and now this person said that he knows someone that is waiting for his. So that makes it 2 lol.
Of course all these kind of promo cds exist in a few hundreds maybe. For record labels, record stores, radio stations, etc. But I meant like literally copies that we know people have.
I actually think that Stick N Move is the most luckily to have been studio recorded. As you said it became Runaway and we also have the Stick And Move instrumental demo, which means the band worked on it for years, so I believe there must be a version of it studio recorded, maybe not the same as the Xero Tape, maybe with a couple big changes but still, I think such version probably exists. And tbh I really hope it does, Stick N Move is my favorite Pre-Linkin Park track.
