I must admit that I haven't been patient enough to time my sim to see if they stop after the two plus minutes or whether they may stop earlier for a queued action. I'm assuming that the sims won't consider stopping until the sequence ends (although they seem to be having a heluva good time, so maybe they won't stop! ). The video demos on the download site ( here, if you're interested) indicates that the dance sequence takes between two and two and a half minutes to complete. I couldn't cancel the action once it started. It's pretty cool! Just a couple of warnings, though. Went in to the nightclub, visting sims would dance and then go about their business. I downloaded this, it works with any stereo, it worked in game but it would delay action with the sim that you were using, (wanted to do on their own).
