1. Buy Echoes: The Best of Pink Floyd
2. Listen carefully.
3. Locate your favourite songs on the collection.
4. Consult the liner notes as to which albums those songs are on.
5. Purchase those albums.
6. When you've gotten through those, purchase Obscured By Clouds, and Atom Heart Mother, because there aren't any songs from either of those fantastic albums on Echoes.
7. Buy the rest of the Floyd back catalogue.
8. Lather, rinse, repeat.
