Pros:
* Easy to install (lol - Joomla 1.5 FTW)
* Nice interface with volume control and standard controls
* Scrolling track info
* Player/Pop up works great in IE7/FF3

Cons:
* Manually editing the XML playlist for each song kinda sucks, especially when other players like Wimpy automatically detect music in a set directory - but this is free and Wimpy isn't so I'm not really complaining
* Inability to seperate tracks by album (or am I just missing something?)
* Set size on pop up (is it adjustable?)

Very simple to use - does what it says it will. Would like to see transparent pop in like previous reviewer commented on, but overall, this plugin is very very nice. Good work!
