Downloading m3u file from i-dose

I tried to listen to tunes on i-dose, but i can't due to some problem which i couldn't figure out. Then i searched for how to download that tunes on to my computer. There are some hints on the net but not clear. Here is the way...
Right click on any of the links on i-dose site, click on CopyLinkLocation. Now in your browsers locationbar where you type url addresses, paste the copied address(Ctrl+V). Here is the trick, chnage the file extention to mp3 from m3u(just edit it in locationbar itself). Hit Enter and save file. Njoy the tunes....Don't ask me for the effect of i-dose tunes :) .
Sorry, the downloaded file is playing just buzzzzz.... i don't know why :) ...
