I am also using this script on one of my sites and you can check that in my signatures. You can buy it from scriptowl.com for just 20 bucks where it was first released officially. There is no such free script I guess.
But just a quick note, as esnips has changed its file sharing policy and have changed its music players, this script no longer supports esnips..the script writer has added ijigg and mp3realm to compensate that and it works just fine again.
In my view its a good script for its value and the script writer is very co-operative too. If you want a site like that, it would be a wise decision to get that script unless you are not from asia, because ijiggs and mp3realm have only English songs collections and very few other regional songs.
