Same heard here. Didn't note times (roughly between 0000-0200z) but by the time you played Cypress Hill and Billy Preston the signal seemed to have settled on 6923 and audio was cleaner. Very cool, noticed the DSB, no/suppressed carrier trick. About equally audible on both USB/LSB, depending on usual propagation shifts.
Thought I heard another station closer to 6925 but it sounded more like the usual pesque jibber jabber around 6925-26 we've heard recently. Didn't sound like another pirate to me, but wasn't clear enough to tell for certain.
Another station was on 6929 LSB at same time but no QRM between you, plenty of signal and audio separation here.
