Maybe I missed it, but it looks like Apple is listing some tracks now for over $1. Specifically, the page for this Russian National Orchestra recording shows up at two tracks, one for $7.49, and the other for $4.97. Each "track" has 3 additional tracks collapsed underneath it, outline-style. The outline thingy is new to me, too.
Admittedly, the $7.49 track is over 40 minutes long, so that's not a bad price, but it's surprising to see Apple going this way. They certainly don't lower prices for short tracks. See the recording of Shel Silverstein's Where the Sidewalk Ends, for example--it's full of short tracks (as short as 13 seconds) for $1 each. In fact, if you were to buy the whole album one track at a time, you'd pay over $46.
