Recommend me some classical music

[Keylow]

I've been listening to a bit of classical music recently, and I'm rather enjoying it. However I know next to nothing about it. So it would be great if some of you guys could recommend me some, be it Handel, Mozart, Tchaikovsky, whoever. I'd certainly like to hear/ know what the most popular and highly regarded ones are. I know it's quite a broad time scale, but if you think it's good then I'd like to hear it.
