I’m working on a small app to manage some mp3 songs. Is there a way to  
scan the mp3 file itself and return the duration in minutes? How would  
I go about doing this?

Thanks,

Hey mate,

Have a look at rmovie. You can get info on mp3’s with that.

Cheers,  
Carl.

I was using [http://rubyforge.org/projects/ruby-mp3info/](http://rubyforge.org/projects/ruby-mp3info/) which worked  
nice,  
untill I discovered it crashes on certain mp3’s.

I will try rmovie now
