What are these songs?

I am looking for two songs, there are no words to them, one is a popular mozart or beethoven like song that in movies and tv shows builds up toward something dramatic or shocking. There may be a chorus singing in the back. 2nd song was played at the season finale of Smallville Season 3 Episode 22 "Covenant" when Clark Kent's mother was running out to the acre and the safe house was being blown up?
