The crab in Oktyabrya seems to be very indecisive. When I play a musicblock for him, headphones are added to my inventory. But then, when the dialogue appears over the crab's head saying something like "Here's a little somethin' for ya", the headphones disappear from my inventory. Did the crab change his mind on if I deserved the gift? This has happened twice with different musicblocks (XS-2 and another), so I'm pretty sure it's the crab's fault. It's not a huge deal, I suppose, but I sure would like to own a pair of headphones (crabphones?) for longer than just a few moments.
