I think this IA song is rather catchy! I've been listening to her stuff lately and she's certainly one of my favorite Vocaloids for sure.
I thought this was a very pretty version of Emotional Skyscraper ~ Cosmic Mind (Byakuren's Theme)
A version of Plain Asia (Keine's Theme) that I listen to quite often when I'm sewing. The music is quite calming for me, especially when I get stressed out.
A little different from the things I usually post, but this mix has a special place in my heart and reminds me of fond memories.
