I have been noticing how US radio edits songs for their length. For instance, on Hawaii's Smooth Jazz KORL 101.1, the short version of George Duke's "Sausalito" is played on Johnny Miro's "Smooth Morning Mix." I have the full (longer) version of "Sausalito" on my iPod. Philippine radio, OTOH, plays the full versions of songs. 106.7 Dream FM in Metro Manila recently played the full version of George Duke's "Sausalito" at about 12:50 PM Philippine Time. It seems Philippine radio is not ashamed of playing full, unedited versions of songs. Are there any good reasons why US radio edits songs for their length? Is editing songs for length done in other countries besides the US? Thanks in advance for any insightful answers.
