I found a nice Esperanto song:

I think the song is about someone who was living in a small town and then had to move to Berlin, which he found was very lonely. His gf told him when was leaving that she loved him or something. Now he regrets leaving and wants to go back to his town. That is what I got out of it. Is that right?

Also, don't forget about this guy. He is awesome:
