This one’s the opposite of last Sunday’s: It’s a huge help to solve the theme early. So let’s see if I can help without giving it away. Look over the set of clues: Many “—” clues and a key clue, 70-across, that says it’s linked to the ten others, obviously, the “—” clues. I wouldn’t suggest going for the long answer first. It’s a lot easier to solve the other way around. The puzzle creator has been pretty clever about covering his tracks, though knowing something about white rap singers would be a big help. I’ll just say this: What’s a dash at the end of a line in a paragraph usually indicate? Ok, one more hint: Sometimes, when what’s shaping up to be the right answer won’t fit, it means there’s a rebus (multiple letters in a single box). That isn’t what’s going on here, but there’s something very similar going on.
Meanwhile, 1o specific hints:
6-Across Cry like a baby: Or a baby cat
20-Across Spanish skating figure: No, not the Spanish word for axel or toe loop or camel, think of the kind of figures in a spread sheet. Which one would you make in the ice?
78-Across It’s a lock: Or an Eli.
121-Across Spirited?: More non-standard than even 101-Across
14-Down Skipjack and others: Think fish.
72-Down Question to a poker player: Or to a dog or cat
91-Down Headlines, as a band: Two words. Clue should probably say “sometimes” as this isn’t always so.
88-Down U.S.S. Ward, e.g.: Every play the game Battleship? Think naval vessel types.
76-Down Where the code of Hammurabi is displayed: Think specific museum, not city or country
