Google's Circle to Search feature has been updated to include a history of previous song searches. This enhancement allows users to easily revisit songs they've identified in the past without having to re-initiate the search process. The update streamlines the music discovery experience, making it more convenient for users to find and listen to songs they've previously encountered. This feature is expected to be particularly useful for users who frequently use Circle to Search to identify music in various contexts, such as videos or social media posts.
