Star Trek: Picard opens with the curious choice of Bing Crosby's "Blue Skies." 1 / 7

And this is direct reference to Star Trek: Nemesis. 2 / 7

Data sings the tune at Riker and Troi's wedding as a gift to the couple. 3 / 7

And then, after dying and trying to transfer his memories into B-4... 4 / 7

B-4 is heard singing the same tune, implying Data's survival. 5 / 7

We now know the transfer didn't actually work, but... 6 / 7

Could the return of "Blue Skies" hint Data is still alive somewhere else... 7 / 7
