10/27/2016 - upgraded the font size calculation for 'medium' and 'large' fonts.

9/24/15 - fixed bug with temporary file not getting deleted.

11/27/14 - fix bug reported by user.

Now looks for iTunes directory on SD cards.
This is probably a better way to contain your music.
- easy to update from your PC (assume it supports SD cards)
- need to be careful with wear on USB port connection (we have noticed problems)
