I gave the cast recording another try. Openminded.
I have listened to the whole thing 5 times now. And honestly, I have been searching for great moments. Lyrically, vocally or musically.
I really wanted to find them, but it was hard. I found 2 little moments. In the opening song at 1.33 Eliza sings "when he was 10, etc, that little part is actually slightly musical and good, even though it's only for a few seconds, including the lines the guy sings after her.
The only other catchy part I found was the line "say no to this". But only that line, the rest of the song goes nowhere.
The rest of the cast recording is one big cheap noisy uninspired r&b nineties amusical rip-off. Sometimes there is one word that tends to go into an interesting melody or harmony but it's quickly thrown away during the next word.
The weakest link of the performers is definitely Miranda, with an embarrassing amateurish quality next to the professionals, who also struggle to make something of the material.
