Legally downloaded music and PDA storage cards

Factual Questions
1

I use my PDA as a portable music player and I downloaded one song (“My Girl is Red Hot” by Robert Gordon and Link Wray, if it matters) legally from WalMart.

My PDA, a Toshiba 330, is listed as a compatible portable player and I am, in theory, allowed an infinite number of downloads to it. And I can download to the PDA, the problem is, I can’t download to the storage card. I get a message saying the license terms don’t allow storing it on that device. Since I only have about 18 Meg of free storage space on the PDA (as opposed to a 512 Meg secure digital card dedicated solely to music), I’d be out of my mind to use the PDA’s main memory.

Is there a legal way around this (I know a pain in the you-know-what way around this which is probably not quite legal, but hey, I could prove I downloaded the song once, not that it would help if lawyers got involved). If not, I think my downloaded song total for my life will be forever stalled at one.

Are you trying to store the music on the card using a seperate card reader?

In my experience the only way to get music onto your large capacity storage card so that the licence is still valid on your PDA is to do it via the PDA. I copied a whole album of music onto my 4GB card via a card reader. when i came to play it it said there was no licence. Then I copied it via the pda. It worked.
