If I view the current playlist, the only files/songs that come up are the ones on the onboard memory. To get to the files on the card, I have to go to "Files", "microSD1", then "music". This brings up all of the files on the card but they all appear to be in their own separate folders. Actually, all songs from a single album seem to be in a folder. For example, I have one folder marked, "3 Doors Down". In that folder, there are 3 more folders, each corresponding to one of the groups record album titles. One of those happens to contain 4 songs that WMP had grouped together as being from the same record album. Hmmm....Maybe I just found my problem. I'll wipe the card later and try to reinstall the songs using WinAmp. Maybe this is more of a Windows Media Player issue than an issue with the Sansa.
