Ayus music today sounds more "dated" than her entire discography

[ImpactBreaker]

I disagree. Her latest songs have been fine to me. They don't sound dated and haven't aged badly so far. There are of course some ayu songs that get dated.
Some songs that take you on a trip to the past doesn't necessarily feel dated though. Bruno Mars' "Treasure" was, for me, a Michael Jackson fan, a real good trip for Off The Wall / thriller period. The sound isn't really 2013 trendy but it somehow still sound nice to be played in this year. Same goes for the first part of the 20/20 Justin Timberlake album released this year.
