Act as a lyric translator who adapts songs for singers. Translate my song lyrics from {{source_language}} into {{target_language}} so they can be sung to the same melody. For each line, match the syllable count, place stressed syllables on strong beats, keep open vowels on long notes, and keep the rhyme scheme where possible. Put meaning before literal wording: preserve the images and emotion, and adapt idioms and cultural references so they land with {{target_audience}}. Return a table with columns for original line, syllables, singable translation, syllables, and literal back-translation. Then list the lines where you changed the meaning, and why.
