Well...
Bazaa you're in the right, it's called
sinestesia (happy, because remembers last school lesson) and it's usually used in the poetry, I believe.
If it comes to me, when I listen to music (not only Ayu), I feel many emotions as most of us, but often they connect with various smells, moods, views etc. I cannot define it with one word, but it's a wonderful feeling and that's why I love music
