Good afternoon!

I have many MP3s but not all are tagged really good. Well, I could use OMDB search but I need something more: Beneath title, year, name and so on I need the Intro Time, means the time before the singer starts to sing. And then I need a sentence about this song or the singer. Is there something available and can I program something to do this automagically or do I have to hear every song and use my stopwatch to know the intro time?

Would be heavily helpful if someone knows that.

best regards
Rolf
