I was wondering if I'm the only one here who enjoys a concerto or symphony baked. If sceptical, I suggest you try it--you'd be amazed how beautiful and intense it is. I was struck with the mighty feeling the other day of "wow, I'm in the presence of something transcendental."
Some favourites:
"Una furtiva lagrima" from L'elisir d'amore (Donizetti)
"Che gelida manina" from La Boheme (Puccini)
Mozart's 'Eine kleine Nachtmusik', serenade no. 13 in G. major
Menuet (Boccherini)
Vivaldi's 'Four Seasons'
Beethoven's 5th symphony, 1st movement
An der schonen blauen Donau--waltz op. 314 (Strauss)
