Next sentence: "Open the music streaming platform and search for “Doordarshan title song” or “Doordarshan theme song”."

Make sure that brand names like Doordarshan are left as is. Then, output the text with the synonyms in syn2 format. The final answer should be the transformed text with all applicable words replaced, brand names retained.

Also, check for any contractions like "you're" becomes "you are", but since we're replacing words with synonyms, contractions might need to be expanded if necessary. Wait, the task says to replace all words except proper nouns. Contractions like "you're" (you are) would be handled by replacing "are" with synonyms. But "you're" is a contraction, so maybe expand it first. For example, "you're in luck" → expand to "you are in fortune".
