Changes

===The Perfect Drug(Complete)===This is the original version that can be found on the ''Lost Highway'' soundtrack as well as some versions editions of ''The Perfect Drug Versions''. It features prominent acoustic guitars playing a quick, ascending riff similar to the chorus of [[The Wretched]]. It is backed by frantic and complex drum machine programming commonly associated with the drum 'n' bass genre, which opens up into simpler patterns for the pre-choruses. The chorus features heavy guitars backed by more frantic drums, while the bridge is composed mainly of percussion patterns and percussive synthesizers and guitar riffs, which build in intensity to give way to a slower, simpler, quieter coda. ===The Perfect Drug (Edit)===Almost equivalent to Complete version (5:15) but shortened by fifty seconds to suit airplay (4:25).
