This video contains the iconic Rickroll meme track by Rick Astley. The lyrics revolve around themes of loyalty and commitment, featuring the artist's signature bassline and 80s production style. Despite its simple lyrics, it remains one of YouTube's most enduring viral pranks.

Notes#

• Handles both manually created and auto-generated subtitles
• Falls back to English if Korean subtitles aren't available
• Returns error messages if no transcript exists or URL is invalid
