I just finished reviewing Echoes, the new compilation effort from Pink Floyd. What a disappointment. I, like many die-hard Floyd fans, find it difficult to take a track out of the context of the original album and enjoy it as a single. So I ask the question, If you could take 26 of the greatest Pink Floyd singles to create your own compilation, what would you include? Beyond that, If you could create the ultimate weed-head compilation CD of various artists, what would you include?
