Any work on expanding the database size?

Go to rockbox and download the Rockbox Utility.  You will need a copy of the fuzea.bin firmware file available here from one of the manual firmware download links.  It’s really dead simple. 

You simply plug in the device in MSC mode and the installer will detect your player. 

Very simple.

I also have discovered that you CAN listen to Rhapsody tracks on a Rockbox Fuzed.

Follow this thread so you can maintain your Rhapsody tracks while running Rockbox on your player.
