I know I've posted a response to this before but possibly not in this particular album. I don't know anymore.
In an case, the inability to download is not something I did personally just to frustrate all of you.

So if you need to take it up with anyone, I suggest you take it up with Multiply. You can contact them by sending a message to SERVICE.
Having said that, like I've mentioned before, there is a work around to that issue. I will highlight it so that if anyone else decides to ask the same question, it won't be difficult for them to spot it.
Simply click on "play the playlist" and allow Windows Media Player to open the songs. Once they are loaded play the song you want to download and let it play. As it is playing, click on "save as".
