This is a good way to spruce up on your classcal music knowledge.
I know about 80% of them.
When I lived in Israel, I shared a room with a Swiss guy who was also into classical music.
The local radio station played a lot of it and would play the piece first, then tell what it was.
So we had a competition going about who could name it first.
I've always loved classical music.
Years ago I dismantled a birch tree.
When I came down, the owner asked me if it was normal practice to sing Mozart in trees.
Turned out I had been belting out parts of the marriage of Figaro while chunking down the tree.
