Question

I am developing a python program which can extract ID3 tags of mp3 files. I am using urllib2 for checking MIME type of the URL (if it is audio/mpeg), after that I need to find information about this MP3 file.

Problem is, I dont want to load that Mp3 file completely in my PC, I just want to extract ID3 tags? so is it possible to extract them without downloading MP3 file completely because downloading will slow down my process?

Please suggest something.

Thanks,

You can do a partial download: Download file using partial download (HTTP) (if the server supports it)

on rereading, and seeing joelhardi’s comment, this is even easier:
