Well I have been trying a few of the radio station sites where Gaslight has played and noticed you can directly download from some of them either mp3 or flv. The flv are usually videos but this would be a lot easier and better in terms of quality to rip the audio from since you just need to strip it and not rely on someone's audio settings being correct. It would be whatever quality the radio station put out.
So anyways here is how I do it. You need Firefox and Firebug addon. For those that don't know firebug is for web developers to debug their websites. It very powerful but were just going to use one part of it.
Once that's installed pull up a website what gaslight played on. I'll use my last post as an example http://www.91x.com/91xaudio/index.php?id=308. Then before hitting play hit the firebug icon in the bottom right of the screen and click Net and Enable. Then hit play. You will see a bunch of stuff going on but you want to look for the line that has a big file loading. If you put your mouse over the Get part it will change and show you the URL. Then Right Click on the Get . for that line and copy the location or open and save it out.
Hope this help.
