Big artwork. Honest badges.

The cover fills the sheet, and two chips under the title say what you're hearing: the file's quality, and whether Android's mixer is in the way.

Tatsumi's synced lyrics on Android for I want to survive by Noyuri: the line being sung in bright, large type, the lines before and after dimmed
The line being sung

02 · Lyrics

Synced lyrics for the track, the line being sung held bright and large while the rest waits dimmed above and below it.
