Oh so many...
SEASONS (Even though I don't really like it now, but it just reminds me of 2 years ago when I would listen to it before going to school)
rainy day (This is one of my first Ayu songs and my personal favorite, so it holds a lot of memories for me)
A Song for XX (This is really the song that made me love Ayu ♥)
Endless sorrow (Just another of the first song I listened to~!)
But I consider songs from Memorial address to (miss)understood classics because they were the first few Ayu albums I listened to~ So I always get hit with a sense of nostalgia whenever I listen to these albums ♥
Secret and afterward doesn't feel that classic to me
And RAINBOW and before feels ancient to me
