I tried that "piaScore" after reading about it here and I found the coolest little thing - if you install it ... try this:
1. call up a file
2. tap the center of the screen to access the top menus
3. tap the video icon on the right side (next to metronome)

Voila!!! A small window pop up with a you tube video of THAT SONG! there are multiple videos available sometimes, too. It a great way to refresh your mind on a style before working on a lead sheet.
No prep work needs to be done - just call up a song sheet with a title. THAT title will pop up instantly. Very cool, indeed!
