(I didn't mention the soundtracks from the movies or games as well as the main themes from the movies or the openings and endings from the series)
These were all albums I've been able to find. But unfortunately, I couldn't find Tenten's theme (it wasn't covered in an album but only as an individual track) which made me wonder if I did find all the tracks from the franchise.
On amazon.co.uk I've been able to find Tenten's theme as well as other themes which aren't covered in the albums above. But since that album is titled "The Greatest Instrumental Themes from Naruto" I doubt that I was able to see every track of Naruto.
