Favorite Ayu arrangements?

[NintendoHTF1242]

Don't know if their is a topic on this x:

But alas, what are your favorite Ayu compositions/background music? For me, it's walking proud (the twinkles are so pretty), Free & Easy (just an epic instrumentation throughout the whole song), and HANABI (that music box just gets to me...). Honorable mention goes to Sparkle, Love song, and Thank U (the arrangement in Thank U is flawless). Although Ayu has a ton of songs that have beautiful instrumentation.

So what about you guys? Ignoring the lyrics and vocal techniques and just listening to the instrumentation, what are your favorite songs?
