In here, I'm planning on looking at an MP3 file, and pulling out its ID3 meta data. The MP3 I want to look at is the file I Feel Fantastic.mp3, intentionally given a file name that is common amongst music collections.

This should really be made into a unit test...

Here's a table listing the meta data I'd like to return (accurate) and what I'm actually able to return.

Tag name	Expected response	Dynamic response
Title	I Feel Fantastic	I Feel Fantastic
Artist	Jonathan Coulton	Jonathan Coulton
Album	Our Bodies, Ourselves, Our Cybernetic Arms	Our Bodies, Ourselves, Our Cybernetic Arms
Track number	2	2/5
Length	03:03 (183 seconds)	183

For future reference, the ID3 analyze function returns something like this:

  ["id3v2"]=>
  array(8) {
    ["title"]=>
    array(1) {
