MySpace is created for humans, not for automated software. Sites administrators dislike robots and take a lot of measures to limit theirs activity. That is why our software masks itself and emulates human behavior.

Humans use browsers to access Internet. Each browser sends its name and version to site when access it. Such process is usually invisible for user, however, site administrator can see these browser self-identification strings (they are called user agent strings). Different humans use different browsers and different versions of the same browser (for example, someone likes Firefox and has Firefox 3, but another man is conservator and still prefer Firefox 2, the third one uses Internet Explorer 7 SP1, etc). However, your software is only one, and all music/video plays are actually sent from the same user agent. Site administrators can learn theirs server log and see that all 1000 (10000, 100000, etc...) plays are sent from the same user agent, and it will be very suspicious.

That is why we need random user agent feature. If you will enable this feature, your software will call itself by a lot of different browsers, and each new song play or video play will look like sent from different browser software. This will hide your activity from site administrator, make if more natural and secure.
