The R&B crooner broke down what this moment means for him Saturday morning when we ran into him at LAX, and he said it quite succinctly ... not only is this a re-introduction to fans (new and old) but it's also an opportunity to make up for lost time ... financially.

Check out his response ... Tank makes no bones about the fact that he's missed out on a lot of dough over the years considering his first 3 albums weren't streaming or on digital platforms. He's not sour over it, but notes a wrong is finally being righted ... and he's glad.

As for Aaliyah's music, and her family's apparent opposition to it being released without their blessing ... Tank says he understands, but that it's perhaps a blessing in disguise -- as he notes, as so many others have, that a whole new generation will get to know her anew.

That acrimony aside, Tank's just happy people will finally get schooled on late '90s/early 2000s R&B ... a chapter from which he DID exist pre-2010 -- and cranked out great music.
