Hello.

I cannot found pull requests on gist files so i wrote here a little pull request to your code, why on line 147 instead:

outfileobj.write(("\t".join(fields) + "\n").encode('utf-8'))

you not uses:

outfileobj.write(("\t".join(field.replace('\t', ' ') for field in fields) + "\n").encode('utf-8'))

it is because if the track name have any '\t' character, the result file breaks when imported to libre office so replacing the tab character by a space character you skip this problem :)

When I ran this I got the following error

>>> python lastexport.py 
  File "lastexport.py", line 87
    except Exception, e:
                    ^
SyntaxError: invalid syntax

the reason was that it was using python3, you have to run it with python2 for it to work.
