I was trying out scenes from a few Blu-rays, including Sin City, Ghost in the Shell 2: Innocence, and The Blu-ray Experience: Opera & Ballet (Opus Arte).
The last is a 50-minute sampler, which is a pretty good way to get a taste of Opus Arte's catalog for only $6.95 (price grew to $7.99 on Amazon.com after I ordered it). If nothing else, at least now I know the name of a familiar piece of music: "Aria - Queen of the Night" from Mozart's "The Magic Flute". Those high notes sure are fun.
Now I'll watch another episode of NewsRadio before Letterman.
