Hmm.. When you go to Islamweb.net and pick a surah you want to save try doing this (using IE, cuz it seems to act weird in Firefox, if you even use Firefox).
Click save. When the pop-up shows up, asking you where you would like to save the file, under the field where the file name is, type in .mp3 after the name. Click Save. It should be an mp3 file after saved. Thats how it is for me anyway. :?
If that doesn't work...then inshaAllah somebody will come forth and help you. :)
