AMPad

From the developer: ""AMPad is just a little tool that sits in your system tray, and as you play songs in Winamp, AMPad will send the titles of the songs (and other optional items, such as time, etc) to either an AOL chat or an AIM chat. Though if you are using AIM, the font/color selections will do nothing, that only works on AOL. It also keeps a log of every song you play, so if you hear a good song on internet radio, you wont have to write it down, does it for you. I find that very useful. You also have the option of sending the title and song name to chatrooms as links to lyrics on SongMeanings.net (the best lyrics site on the web).""

Requirements:

Windows 95/98/Me/NT/2000/XP, Winamp 2.x, 32-bit AOL or AIM
