I think LOVE is so CLASSY and LUXUOUS. For some reason the songs in the album makes me think of places inside a huge house or high class social events. Songs like aroma, makes me think I'm taking a bath on a huge bathtub inside a very beautiful mansion bathroom, with all kinds of expensive fragrances and stuff. I know it's funny but that's how I feel when I listen to that album. Maybe it's because of the jazz style.
MUSIC sounds more SENTIMENTAL and MYSTERIOUS in my opinion, it makes me travel through different and exotic places, specially with songs like Kumo no Ito.
I think vocally Mika did a better job in the LOVE album though. Her vocal performance in songs like Fed Up and FAKE could have been worked better in a way as I don't really have this complaint in LOVE...not that I remember right now.
I can't choose my favorite though.
