Design a vibrant and nostalgic Spotify playlist cover titled 'Harin Favorite v2.' The cover should evoke the essence of the 90s to 2000s Kollywood music scene. Incorporate elements that symbolize iconic music directors like A.R. Rahman, Deva, and Ilayaraja. Use a retro color palette with a blend of classic music symbols, such as vinyl records, cassettes, and musical notes. Include subtle references to popular albums and soundtracks from that era, all wrapped in a sleek, modern design that reflects a personal, curated collection.
