According to iTunes, these are the top ten songs I've listened to:

1. Tsuna Awakens from Katekyou Hitman Reborn!
2. Imposing Visage from Tales of Destiny
3. Suoh Mikoto from K
4. A Despair-Filled Farewell from Shadow of the Colossus
5. Saber's Edge from Final Fantasy XIII
6. White Light from Tales of Zestiria by Superfly
7. Influence of Deep -CM Version- from Parasite Eve
8. Battle: VS Cocytus from Wild ARMS 2
9. Battle 2 from Final Fantasy III
10. Uragiri no Yuuyake from Durarara!! by Theatre Brook

I was... very surprised by this. I think at least two these, White Light and Uragiri no Yuuyake, are up here because I left my iPod on repeat all night, but I cannot explain Tsuna Awakens. I mean, I like the song, but not that much. And I don't remember listening to it that many times. A Despair-Filled Farewell yeah, but not that.

Battle 2 should be in the top three and the fact it's not completely disgusts me.

Could not find the OST track for Tsuna Awakens on youtube, hence the orchestra recording. Why not? Did someone finally claim copyright? For Reborn of all things?
