Soundtrack of Naruto and Naruto Shippuden
An extensive list of the music used throughout the entire Naruto franchise is available on the Naruto Wiki.  This includes a full list of:


Openings
Endings
Various soundtracks at different points in the series
Movie soundtracks


As a fan of the show, I would strongly encourage you to purchase the media from legal and reputable channels when possible.  As an example, here is an Amazon link which points you at the first soundtrack; from there, you should be able to track down the others.
