Make multiple templates for site (new one for many pages)
Drupal has flexible theme system. You can create different sections of your site and theme and select dedicated template according to path. This is what I am suggesting you.

e.g. your site has different pages(paths) targeting different sections.


example.com/music                   (page-music.tpl.php)
example.com/artist                  (page-artist.tpl.php)
example.com/artist/profile/%        (page-artist-profile.tpl.php)
example.com/store                   (page-store.tpl.php)
