Is your SD card encrypted? Then update to the latest beta

Without examining the log, I'd guess that some of your files are in a different location. Perhaps try 'Select SD Card' rather than just the Music directory?

Did you scan the files into MMA (from Options)?

I have just installed MM on my phone. I click on 'albums', then the folder on the sd card where I store my music. I can see no files there, just one sub-folder. Nevertheless, I click on "select Music'. I go back to the album view, the small circle at the top moves for a little while but nothing happens and no albums are detected. It's not like MM doesn't see the sd card at all, because when I go to 'podcasts', all my podcasts are there.
