Currently Amarok bundles liblastfm in lastfm/lastfm. In 2.1.1 we are going to 
switch to externally depending on liblastfm ( 
http://github.com/mxcl/liblastfm/tree/master ). I have it working in a local 
git branch, and will push it when 2.1 is released. 

So, you'll be able to use that. It has the fingerprinting support built in (if 
the lib is built with it)

There is no way around having the fingerpinting require libfftw. Amarok 
requiring libfftw is different though---we can talk about this.

No, this is a bad idea. We actually went through the rmb this weekend in a 
group and carefully removed all non-essential options. Cluttering it is not 
the way to go. The GUI for this belongs, if anywhere, in the Tag Dialog. It's 
just another way of guessing tags after all.
