What's the song that plays when Naruto and Sasuke fight with Rasengan and Chidori in episode 216? In Naruto Shippuden episode 216, at around 7 minutes, there's a song when Sasuke and Naruto fight with Rasengan vs Chidori.

What's that song?
It sounds to me like Samidare (Track 28 of Shippuuden OST 2).

Note that parts of this track also sound vaguely similar to Ochibabune (OST 2 track 26), Yamagasumi (OST 2 track 22), and Utsusemi (OST 1 track 7), so it can be easy to confuse them.

Incidentally, Utsusemi was playing in the immediately preceding scene.
