Can you recommend any clical music compilations for my taste?

I love clical music, but I don't know that much about it. I love ballet music (the music to Swan Lake and the Nutcracker), but also Mozart. I'm not as keen on Beethoven, I find it too dramatic or aggressive, I like music which is heart wrenchingly beautiful and you can feel it moving you but isn't sad or agressive or too dramatic. I want something gentle or inspiring, yet also relaxing. Suggestions please? :)
