First of all. What chief-adfp mentioned, is noncense. There are a lot of sites using it without any trouble at all.

Second of all, BabStats can't do a lot of stuff Now Playing can. A little list:

a. BabStats has to update the database all the time. It is via database, thus not realtime.

b. You have to have BabStats running, to have server status.

c. It can only retrieve half the information Now Playing can. For instance it doesn't tell, which page it is hosted on.

d. Now Playing is not by ip, BabStats is. Meaning Now Playing does not require 1 person to host it, but all members can..

e. BabStats isn't realtime but ever few seconds or so...
