Ofcourse. Some years back I did learn Pascal and then some C (most of it 
gone now I'm afraid) and I think I have some small problems realizing how 
"obvious" Python can be at times. The "if not mp3.endswith("\n")" is a 
brilliant example of that. It sounds like something you could throw out in 
a conversation with the wife during dinner! I need to "beam" my mind to a 
higher level I think!
Thanks again Michael
