Actually I do like what KungTunes can do... I was able to integrate into my site's template with full creative control, which is great.. However, I have some issues with the program itself.
If I want it to automatically upload the itunes data whenever I start playing music, I've got to set the preferences to "auto-start timer"... but when that's set, it automatically opens itunes on startup and starts playing music automatically. Most mornings I turn on my computer and leave it to go do other things while it's booting up... and when I get back it's already started playing the first few tracks in my itunes library and I have to pause it. It's messing up my audioscrobbler data by saying I've listened to the first few songs in my library way more than I actually have.
But when I turn "auto-start timer" off, I've gotta remember to bring kung-tunes to the front and manually activate the timer every time I start listening to music, and then restart it again every time I pause itunes and start it again.
Minor inconvenience... but it got annoying enough for me to have to stop using it. I'm still looking for an alternative...
