I admit to having owned a Glass CD or two. Even so I once heard a joke that goes "Knock, knock. Who's there? Knock, knock. Who's there? Knock, knock. Who's there? Knock, knock. Who's there? Knock, knock. Who's there? Philip Glass." and felt that right or wrong adequately covered some of his work.

To be fair musical tastes change over time; I found myself bored and restless relistening to some old Tangerine Dream favorites.
