Do I need an mp3 player to record for Pure Bug?

Hi,
Firstly, this is not a wind-up!
I am about to buy a DAB clock radio today (see my other post in DAB) and I'm getting a Pure Bug Too, which, apparently, will play mp3 music off a card. (I assume like the one in my digital camera?)
What I'm wondering is: Do I need to buy an mp3 player so as to record music on, then put the card into the radio? Or, is it possible to put a card in the radio and download some music from my computer straight into it? (Yes, I know, DUH!, but I'm an old git who hasn't got a clue!)
Any help with what mp3 player to get, should I need one, would be good, though I doubt I'll ever use it for anything other than music for the radio should it be necessary.
I've posted this in the mp3 section too.
Many thanks.

All you need is an SD card (I got a Viking 1GB from ebuyer for £12 delivered)

When you have this you can put it in a card reader attached to your computer (if you have one) and drag and drop your mp3s on to it. Then put it in the bug and listen!

Alternatively if you don't have a SD card reader you can connect your bug to your PC with a usb cable and then drag and drop the files to the SD card (after enabling USB access in the bug menu). Or you can buy a card reader - about 2 quid on ebay.

I think it's probably easier to use a card reader instead of connecting your PC to your bug. I have a laptop, but it still seems like a hastle to do this - and the bug doesn't come with the correct cable so yu'll need to buy one.
