Files in MUSIC folder showing up in the PODCASTS menu

I’m not sure why, but it has just started happening that all the mp3s that I have copied to the MUSIC directory on the Clip, do not show up in the Songs menu.  Instead, it is howing them as Podcasts.  What is the reason for this?  I am doing just a drag and drop of mp3 files.

All files which are tagged as “Podcast” under Genre will only show under Podcast of the Sansa. If you want them to show under Song list, simply change the Genre.
