Do you use firefox?
if so, what i did is grab the plugin called 'downloadhelper', and install it. should be able to find it on google or mozilla.com
then, once installed, go to playlist.com, type in artist name - song title and play the file off the website (play button). The download helper icon will spin when media is streaming in your browser - click the drop down and save the file. You have to rename it whatever you want.mp3. Make sure you add the extension mp3 or it wont open.
Usually the songs are 192 or even 256k bitrates, some rarer songs may be crappier quality..
Sounds like a lot of work but once you do it once its easy. Wayyy easier than opening a program if you want just a single song once in a while.
