We don't actually know that FML is before the catastrophe - CL0 probably is, and Wordplay probably is as well, but FML's place on the timeline is officially unknown. That said, I do think it's before.

Of course, what I was meaning to say wasn't that Irina was necessarily singing during FML while possessing this Rin - the two songs may be during different points in time, and Irina's repeat of the lines and melody of FML are more thematic than literal. The melodic and lyrical callback only begins after Irina's soul is implanted in the cat, allowing her the ability to take over another person - with my theory in mind (and I note that this is like, 99% speculation and should be taken with a grain of salt), this would be the point (with a slightly accelerated timeframe, of course - the space between the verse and the chorus logically would probably have a timeskip because... well... somehow I don't see a stuffed cat doing experiments) where she takes over another person.

Irina had just been implanted with the next ghoul children when the catastrophe occurred. She was in the Royal Institute at the time, and therefore if any other people were around who survived (say, an underground level of the facility) would likely be a scientist.

With that in mind, it would be like this:

Wordplay, CL0, FML - before the catastrophe, sung by this theoretical Rin character who is being raised by the scientists behind Project MA and assisting in the experiments.

Song I Heard Somewhere - during/after the catastrophe, sung by Irina. The first chorus of the song occurs directly after possessing this Rin, and is why the callback exists - now she has "become" this girl, to some degree, the song repeats her lines and melody from FML to cement the connection and that this is the body she is using. (Also, we do know that the Swap Technique is imperfect and that the original body's conciousness could resurface, so the repeated lines and continuation of Seth's experiments could be a remnant of the girl's original personality.)

Though, again, a lot of this hinges on some very specific things - that this Rin exists, that she survived the catastrophe to be possessed - and while I feel like it would explain a lot, I recognize that it's highly speculative and involves a lot of logical leaps and inferences that could and likely are incorrect.
