Well, just decided to grab the song from one of the episodes and do a little tweaking to make the sound quality better. I have also included the lyrics which you can see in episode shows as well as an album art which I took from the net. Here's the download link via RapidShare. Tried it on my iPod Touch and sounds good enough for me. For other Naruto audio files, go here.

I looked for a way to embed the song in this post but I can't seem to find any, so I have posted the lyrics instead. I also uploaded it to imeem and embedded it here, I am not sure if this will work.

Habataitara modorenai to itte
Mezashita no wa aoi aoi ano sora
Kanashimi wa mada oboerarezu
Setsunasa wa ima tsukami hajimeta
Anata e to idaku kono kanjou mo
ima kotoba ni kawatteku
Michi naru sekai no yume kara mezamete
kono hane wo hiroge tobi datsu

Habataitara modorenai to itte
Mezashita no wa aoi aoi ano sora
Tsuki nuketara mitsukaru to shitte
Furikiru hodo
aoi aoi ano sora
aoi aoi ano sora
aoi aoi ano sora

NOTE: If you want the song that comes with the lyrics and album art, download the rapishare file, not the imeem file.
