Start in internal/pkg/lyrics/lrc.go at line 119, then trace how lyrics.New is called from tui/view/song/song.go:290. Reproduce the reported out-of-range panic with the affected LRC input and inspect the parser's indexing assumptions. Done means the input no longer panics and the behavior is covered by an appropriate regression test.
