From what I can tell they use coding that works only in IE to embed the player on the side of the browser. Are you clicking on the "listen (windows media player)" option? With IE it gives me a choice whether to embed the player on the side or launch the external player. Firefox only launches the external player.
Although all is not lost because if you choose the first option "listen (AudioRealm Player)" then it launches a popup window that has all the artist information on it. It will ask you to test your internet speed connection but if you already know it like cable, DSL, etc then just skip the test and manually choose it yourself.
After that it will give you the option to embed a player into that popup window or use the external version of Windows Media Player, etc. You also have to check only Windows Media Player or the other choice but not both and then click next. Here's where it gets a little tricky, so it might be good for you to try it while reading because it would make more sense this way.
I've tried this website on both Mac and Windows XP and it seems that on the Mac the embedding works but not on XP even with IE. That's probably because I had to manually install Windows Media Player in the past since it doesn't come installed with Mac computers for obvious reasons.

Usually installing or reinstalling audio players will install the necessary plugins for all your internet browsers. Another factor is that my Mac has Media Player 9 installed while my XP has Media Player 8.
Anyway, if the embedded player doesn't work then click on the "launch external player" option at the bottom of the popup window. This will launch your audio player but will keep the Auralgasms popup window, which has all the artists info you wanted.
I know that might have sounded complicated but it's really not. It's a lot easier to try it out then to explain.
