Give me your recs!

I love classical/instrumental/opera/choir music (well mostly baroque, but that's only if we're getting into specifics) and I listen to it a fair amount. Ironically, I'm not one who memorizes everything written by a composer. Heck, sometimes I'll listen to a piece more than once and not even know the composer or even the song title.

Anywoo, I'm sure I'm not alone. If you're up for it, please link me some of your favorite pieces (any era/genre ... medieval, renaissance, baroque, opera, classical, romantic, 20th century, contemporary, movie scores, etc.)
