classical music list

I like some classical music, and sometimes I hear it in an Ad, game, tv, film etc, but have no idea what the piece is called; you can't exactly look up the lyrics in google! Anyone want to help me build a list of famous/well known classical music?

adagio for strings - Samuel Barber; Platoon
Ride of the Valkyries - Richard Wagner
Canon in D - Pachelbel
Rondo Alla Turca - Mozart; Dynamite Dan (spectrum)
Carmen (not sure what part) - Bizet
Spring - Vivaldi
Blue Danube - Johan Strauss; Frontier: Elite 2

Toccata & Fugue in D minor (the saddest of all keys) - Bach; Rollerball
