Seems like you forgot a Minuet or something went wrong with sets. It should be +33 ATK (13 from V, 11 from IV, 9 from III).
For me:
1958 ATK in TP set with MC songs
1991 ATK in TP set with Lough songs
With Crooked 11 Chaos:
3502 ATK with MC songs
3562 ATK with Lough songs
With Grape Daifuku+1 & Crooked 11 Chaos:
3563 ATK with MC songs
3622 ATK with Lough songs
Keep in mind:
ATK from food doesn't scale with Chaos Roll, Indi-Fury, Berserk, Last Resort, etc.
ATK from songs does scale with all that stuff.
My results above only show Chaos+Minuets, it would become more significant if you consider Indi-Fury, Marcato, or SV. Also consider that this loss of atk isn't just for you, but for every member of the party with those songs on, so the impact of using MC is 3-6x the differences marked out above, or worse with Fury/SV.
So...you can't really replace 33 base ATK from songs with food. I mean, I guess you TECHNICALLY can, but it will take a disproportionate amount of +atk from food to gain the atk you're losing from the songs.
TL;DR: In my opinion, if you have a Gjallarhorn or St5 Lough, you should only use MC if you have to (because of nitro problems) or to extend SV songs for another 3~4 minutes. Other uses are just lazy and more impactful than you might think by casually glancing at the Minuet page.
