Thanks for your reply! Yes, bad song choice, but that was not the problem.
The problem was that I lost the settings, and no amount of installation could bring them back.
Apparently, one really needs a tick next to the "Time out" box and have its value set on something larger than zero. As it was, Last.Fm Node was not waiting long enough for last.fm to return (takes just over a second for me).
Another problem with the settings I noticed is that the box "limits the available tracks" should be equal or higher than the "number of tracks to enqueue". Logical once you understand what is happening, but would be easier if the tooltip contained that info.
Great log file though!
