title: Regular expression to extract the year from a string
body: <p>This should be simple but i cant seem to get it going. The purpose of it is to extract v3 tags from mp3 file names in Mp3tag.</p>
  
  <p>I have these strings I want to extract the year.</p>
  
  <pre><code>Test String 1 (1994) -&gt; extract 1994
  34 Test String 2 (1995)" -&gt; extract 1995
  Test (String) 3 (1996)" -&gt; extract 1996
  </code></pre>
  
  <p>I had <code>^(.+)\s\(([0-9]*)\)$</code> but obviously its not giving me the results i was expecting. You can say that im not very good with regular expressions.</p>
  
  <p>Thanks in advance</p>
