Go with the crawl you like best and use keyframes for the music sync. I’m doing crawls for Hal’s prequels and he pointed out the way he wanted the end of the crawl to sync with the music so I inserted an extra key frame for the end of the last paragraph. You want sync for each paragraph though, so maybe it’s harder to cheat in that case.
You can also make a difference with the way you format the text. You can reduce or increase the number of lines in a paragraph by changing the letter and word spacing and even the letter width to fit more or fewer words on a line.
