There are a couple libraries that ease that[1].  Matters are
complicated by the fact that there are two different versions of ID3
tags, v1 and v2.  However most of those libraries should handle them
just fine.

Also, I don't believe that the playtime length is actually encoded in
the file itself, so you might have to do some calculations to find
that.  I've wondered this myself and would be interested to learn
more.  You might look at[2] which seems to offer code using one of
those modules.

Based on the two links, it looks like Mutagen might be the first stop
for getting both parts that you need.
