Itunes Song Progress Bar

So i have the song name and artists working fine, now i want to set up a progress bar.

I have the Song Length printing to a text file, how can i call the song length in relation to the current time to set up a bar,

I'm thinking some that measures current time, format seconds, filling up a horizontal bar.

The time should reset every time the song time changes

i guess it could be done using the other song data.

I'm hoping some sort of loop that loops while the song name stays the same?

any ideas?

thanks.

p.s. Song Data can be recorded using a vbs script:
