Sometimes picking the searchable musical tags for these countdown posts is easy. "Indie pop" ropes in Los Campesinos! and Dowling Poole and Gentleman Auction House; "alternative rock" has both recognizable sonic characteristics and MTV certification for the Pixies and Mary Timony; "heavy metal" clearly fits Queensryche and Savatage. Joni Mitchell's "the Jungle Line" was tricky, but once I thought of "experimental pop" I immediately recognized several occasions I'll have to re-use it later in the countdown. James McMurtry ought to be straightforward: he's a country music songwriter, albeit a culturally rebellious one, so certainly here's the first use of the "folk/ country" tag I'd intended all along. But ideally you've clicked the link to play the song, in which case you can also sense the incompleteness of that label.
