Nokia 6230

I just purchased a 512KB MMC card for my Nokia 6230 and downloaded from my computer a bunch of MP3 songs. I placed them in a folder on the MMC card. Though through Media player I can access individual songs, Music player is not finding any songs. Does anyone know if Music Player can be configured to look for songs on a folder on an MMC card? Or do I have to put all the songs in the root directory of the card?

Also, does anyone know of a commercial stereo headphone adapter for the Nokia 6230? I have seen a number of home made solutions, but other than Belkin's universal 2.5 adapter, there doesn't seem to be any solution for 3.5 headphones.

Thanks in advance for your assistance.
