synchronizing lyrics to music
do lyrics (text) to voice (which is much easier than voice to text),
then compare voice synthesized from lyrics with voice in music
to figure out when lyrics should be sung/said.
One only has to compare synth voice with music voice,
without having to understand what is being said.

Some guy has analyzed Beatles songs.
Make a program that judges the Beatleness of a song.
Then use genetic algorithms to randomly tweak a song until
it is a good Beatles song.

Are Bach's patterns easier to see?
Make a program that judges Bachness, then make new Bach'ish songs.

What to use to make GUI Python programs?
tkinter is the de-factor standard for that.
Is there better stuff now?
Should one skip making GUI programs, and make web server/client stuff?
(kindof like how Ipython went from having Qt GUI to web GUI)

wp:tkinter mentions several other GUI libraries for Python.
Would Pygame be good for someone dealing with sound/music?

write native GUI apps
    need to rewrite for:
        iOS
        Android
        Linux, MS Windows, and Apples by wxWidgets

or write app once as web server, and use from browser to use.

Are native GUI apps more appropriate for apps needing serious
CPU crunching or local storage needs?
