Featured on Britney Spears’ debut studio album …Baby One More Time, “Sometimes” was released as her second single on April 13, 1999. The lyric references a shy girl who is hesitant to express her feelings to her lover, and is firmly of the teen pop genre that exploded in popularity in the 90s with bands like ‘N Sync and The Backstreet Boys. “Sometimes” was a worldwide hit, charting inside the Top 10 in eleven different countries. Key change arises out of silence following the bridge at 2:47, shifting the tune a half step higher for its concluding chorus.
