# Data Processing Layer

**i. ETL Pipelines:** Extract, transform, and load raw data into structured formats for analysis.

**ii. Natural Language Processing (NLP):** Parse unstructured data like song lyrics, video descriptions, or social media posts to extract sentiment and themes.

**iii. Time-Series Analysis:** Model temporal patterns in user behaviour (e.g., weekend binge-watching vs. weekday playlists).
