Query: Bonus tracks kill the mood

The addition of the bonus tracks takes away from the impact of this album. The art of the album is one of the strongest aspects of music. It's not enough just to write good songs. Thoughtful, effective album structure coupled with consistent, overarching themes enhances the musical experience. You wouldn't add bonus tracks to Abbey Road now would you? All albums should be treated with the same respect.
