That really only affects the first song in the macro though. For mine I actually completely remove the pause from the second line, so they look like this:
/pause 30,/stopsong
/cast 1
/stopsong
/cast 2
I used them far more when I was leveling up, because as OP pointed out: fuck manually twisting 4 songs for hours on end. I find at 60 I melee very very few mobs, and since I wouldn't trust the pause when twisting something like resist songs on raids I typically use a trusty manual 3 twist so that nothing ever drops. If for some reason I was in a group at 60 on my bard where I would be meleeing (lol weapons) I would probably use the buttons again.
