IMO, if there are issues with recollecting the songs, just put it down for a bit. It's only been a few days, you're not going to remember all the songs. I know I don't yet other than a small handful, but in time, I will.

Ayu's tracks have never really been earworms, at least to me, as a whole. She has had poppy tracks that have amazing hooks/choruses, but most artists I find that do the sort of music she does (aka what she likes, with specific goals for each song) put the "catchiness" on the backburner.

And honestly, aside from a few tracks every album, it always takes a while for me to remember the songs without listening to a bit of it first. It's not that strange unless you have an amazing aural memory.
