Tag Cloud does not reflect tag count, itunes tagger

so, i am currently working on http://www.last.fm/group/Last.fm+Web+Services/forum/21604/_/285676/1 and it actually works quite well. (btw, feel free to give me some feedback in that thread please, it's about a script to tag mp3s in itunes using the last.fm data)

however i found something weird. first of all Jimi Hendrix - foxy lady is heavily tagged as "metal" (absolutely can not understand that), the interesting thing however is if one compares the xml data with the tag cloud of last.fm

the xml (http://ws.audioscrobbler.com/2.0/?method=track.gettoptags&artist=jimi+hendrix&track=foxy+lady&api_key=b25b959554ed76058ac220b7b2e0a026) states
classic rock - 566***
......
metal 680***

whereas the tagcloud on http://www.last.fm/music/Jimi+Hendrix/_/Foxy+Lady/+tags shows a very little metal in comparison with metal (that actually has a bigger count)


btw, the xml is not even correctly sorted to count in this any other cases...?!


i figured the size of an item in the tagcloud relates to the count, or am I mistaken.
either way, Jimi aint no metal...
