Read ID3 Tags of Remote MP3 File in Ruby/Rails?

Question

Using Ruby, how can one parse the ID3 tags of remote mp3 files without downloading the entire file to disk?

This question has been asked in Java and Silverlight, but

Answer 1

you would at least have to download the last blocks of the file, which contain the ID3 tags -- see ID3 tag definitions...

if you have access to the files on the remote file system, you could do. this remotely, and then transfer back the ID3 tags

Edit:

I was thinking of ID3 v1 tags -- version 2 tags are in the front.
