In Naruto Shippuden episode 6 "Mission Cleared", there is a song at about 8:20 where Iruka treats Naruto to a bowl of ramen. The music plays when there is a flashback to Naruto asking Iruka to try on his headband. The song sounds instrumental and happy.
The same song is at the beginning to episode 2 before the title scene/Japanese rock music plays. The song I am looking for plays during a happy flashback. I have spent an hour looking for this song but I can't find it anywhere.
