Sansa Express doesn't see new mp3s


I bought the Sansa Express 1 GB last week and added 135 mp3s to it, yesterday I added another 25 mp3s but when I play the Sansa Express it only shows 135 songs. I connected it to the computer and can see the 25 mp3s in Sansa via windows explorer but when I play it, it only shows 135 songs what could be going wrong? All the songs are in the same directory.

Thanks in advance.

I just happened to run across this problem. Do you run the SE in MTP? If so, then just re-sync it and it should show up after. If that doesn’t work, then reformat and then sync again.

As for MSC, I can’t really help you there. Just make sure your ID3 tags are filled.
