Please describe the problem:
Tracks from the Jamendo plugin, which get streamed over the internet rather than playing from file saved on the hard drive, do not seem to get submitted to last.fm (via the last.fm plugin), as they show up neither in Rhythmbox's statistics nor on my last.fm profile.

Steps to reproduce:
1. Enable the last.fm plugin with a username and password
2. Play tracks from the Jamendo library via the plugin
3. 


Actual results:
Played tracks do not show up in the last.fm profile.

Expected results:
All audio media played in Rhythmbox (as long as they have the appropriate tags) should get submitted to last.fm

Does this happen every time?
Yes

Other information:
This may have something to do with the fact that the slider (the one that shows how far into the track you are) always stays at zero when playing tracks streamed from Jamendo.  It is my understanding that tracks only get submitted to last.fm if at least half the track has played.
