What are some clical songs that everyone should have on their iPod?

Hooked on Clics by louis clark conducting The Royal Philharmonic Orchestra.it was released in 1981. louis clark made this album upbeat to try and get younger people interested in clical music. go on youtube and see if you'll like it. There's also Hooked on Tchaikovsky but I never got to hear it. I would imagine it's also good. I love Hooked on Clics and even if I'm not picked as your best answer, I hope you will love it too. I always hear it in my doctor's waiting room being played, thank you and good luck finding what you want for your iPod.
