Feature Request: Random duration in a set range for playlist items

[Fuzen777]

So what would be interesting would be to set a duration range for a playlist item.

Let's say you set it between 10 and 15 seconds. Each time the item is played, it would be randomly during 10 to 15 seconds. That would help for the randomness of the thing and prevent the need to create multiple copies of the same item with different duration.
