Unable to do timbre analysis on own tracks

Hi there,

I was wondering if it is possible to do a timbre analysis of my own tracks. I have done timbre analysis successfully with tracks of popular music, but not with my own recordings. I want to get the timbre data for 'x' instrument and compare it to 'y' instrument, etc. But I always get the following messages/ errors. Of course, I do not know what they mean. I'd appreciate any help.

Traceback (most recent call last):

File "E:--------TestTimbre(test).py", line 77, in song_search = song.search(title=t)

File "buildbdist.win-amd64eggpyechonestsong.py", line 550, in search result = util.callm("%s/%s" % ('song', 'search'), kwargs)

File "buildbdist.win-amd64eggpyechonestutil.py", line 201, in callm params = urllib.urlencode(param_list)

File "C:Python27liburllib.py", line 1326, in urlencode v = quote_plus(str(v))

File "buildbdist.win-amd64eggpyechonesttrack.py", line 115, in str return self.title.encode('utf-8')

AttributeError: 'Track' object has no attribute 'title'

thanks in advance, -J
