Impossible to record streaming audio, please help.Need direct sound recorder for Mac.

Okay, first of all, I'm new here, and I have searched the forums and have found no answer. I need a free streaming audio recorder (Preferably works with Mac), that just records from your sound card (Anything like computer thinking, or a mouse click, or pulling down a window).

REPLAY MUSIC DOES NOT WORK, because you need a FLV file to drag into there or a URL. I need a program that has just a record button that you press and thats that! I don't want all the menus and the urls and the files, I just need something that can recored anything that makes a sound. Like just playing a Youtube video.

Please help me by recommending a software, hopefully not related to Replay Music, that is free and works with Macs... Thank You.
P.S. It must be Free and works with Macs.
