2007 Billboard #1s were 3% Introduction

I’ve been doing WAY too much thinking about the Intro music analysis.

With Last.FM and Youtube, I got the numbers for the 2007 Hot 100 Number-One Hits

2007’s average introduction length was 3%.

Notable information:

  • Average song length was 4 minutes and 25 seconds
  • Kanye West – Stronger had a negative introduction
  • Maroon 5 – Makes me Wonder had the longest intro

I’ll be running several more years. My prediction: this experiment will show society’s attention span has gone way down, and further prove that popular music sucks. =)

Metallica’s And Justice for All Album: 21% Intro

I’ve been thinking a lot about the concept of an intro in popular music. Do long, non-vocals introductions work? Are they common?

An intro time is the number of seconds of music played before vocals enter the song.

The Intro Ratioâ„¢ is the number of seconds of an intro divided by the songs total number of seconds.

There are cases when this ratio can be negative. Think songs starting out A-Capella. Instrumental songs need not apply.

Since the thoughts were originally spawned by Metallica’s unnecessarily long intro to “King Nothing”, I thought I’d analyze a Metallica album.


An instrumental song, “To Live Is To Die” was omitted.
