May I barge in with a random list...? I don't quite remember the ordering of PoFV levels but every single one of them fails almost inevitably... out of the list here. Restricting to shooters after TH6 otherwise takes tooooo much effort to write...
Title: PoFV, all others make some sort of sense...
St1: erm...UFO...? I found all stage 1 themes to be relatively good
St1B: SA, as above none of them fails too badly
St2: UFO again... this time more fitting for the title
St2B: EoSD. Sorry Cirn9 but this one is for you
St3: MoF. Maybe because I didn't like Nitori the slightest bit... And Keine's level narrowly escapes doom
St3B: Mof. Still... Couldn't find anything worse, perhaps.
St4: IN. A themeless...theme?
St4B: PCB. Phantom sisters needs a resit in their musical tests... Not even remixes do this theme justice.
St5: SA. Maybe just haven't got used to the new musical style yet.
St5B: PCB. Erm Ancient Temple is great, but this one is just... meh, I'll listen to the IaMP version...
St6: SA. If I had to make a choice... then it will be this, all other stage 6 are generally epic
St6B: IN(6B). Sorry NEET but this goes to you for being a NEET.
Extra: UFO. Maybe 30 into the future I will appreciate it...?
ExtraB: UFO. Screvv you for mocking Flandre;'s one!...... Poor Yukari comes close second.
Ending: SA not for a particular reason
That's all perhaps
