Hmm, didn't find much but
this page suggests she probably wasn't keen on the first remix album's title
"its title is "AYUMIX". Sorry. The producer decided it, too. Sorry. Please forgive for the sake of Max Matsuura"
but did say
"I think [it is] very good, as we did our best".
Since she's usually silent on the subject, we might assume she's either neutral or not very keen on them generally.
If she actively liked that style of music the originals would probably be influenced by it more than they are.
