&gt;It&#x27;s kind of like asking &quot;what do I have to do to make my song a #1 hit?&quot;<p>Sure, but it&#x27;s also kind of like asking - Given the fact that all these songs are number one, could we extract some common features?<p>Maybe you&#x27;ll find out that songs have to be shorter than 3 minutes or nobody plays them on the radio, or that they have to be dynamically compressed within a certain frequency range because most people listen to music on hardware that does not reproduce certain frequencies very well, or that having a weird time signature makes a song unpopular, etc.<p>&gt;I wouldn&#x27;t want to work for anybody that trusts people who are too petty or too clueless to make good hiring decisions.<p>Hah, that would exclude a large portion of the professional software industry !
