You might also look at the file set the lame project has used in tuning 
their encoder. Many of these are quite difficult to handle:

And a small suite used in some of the MPEG development:

Of course it is also important to just test with a diverse set of
music; anecdotally many encoders have been largely tuned by one
or two people with good ears using a handful of favorite tunes, with
only occasional feedback from more objective testing.
