The song coverage is more varied than I’d thought. For example, Warren Zevon’s Excitable Boy has all three levels of coverage. “Johnny Strikes Up The Band” has line-by-line lyric tracking, “Roland the Headless Thompson Gunner” has no lyric tracking, and “Werewolves of London” has syllable-by-syllable lyric tracking.
“Werewolves of London” is in the Sing: Classic Rock playlist, for what it’s worth.
It seems more and more like the process that generates a Sing-compatible track is either manual, automatic but time-consuming, or costly in terms of licensing. Otherwise surely you’d want every album with a playlist song on it to be fully enabled, to give explorers like me the sense that there’s a ton of coverage?
