Really,I don't know the difference between classic and popolar.Maybe one of them is new and another is old.I have no conceptions about them.So I like what I like.

you really can define them in the light of time or period. sometimes, classical rather than classic music includes opera, chamber music, choral pieces, and music requiring a full orchestra. roughly speaking, it can be even dated back to around 10th century. but classical music what we talk today is mainly limited to the works of such musicians as Mozart, Haydn, Beethoven, Bach， Brahms，Tchaikovsky，etc. , whereas pop music is the production of last century, really modern time.
