MusicLM by Google is a dataset containing 5,521 music examples, each labeled with an English aspect list and a free text caption written by musicians. The aspect list includes details like genre, instruments used, and vocal characteristics, while the caption provides a detailed description of how the music sounds. These labeled examples are 10-second music clips from the AudioSet dataset, allowing users to explore and analyze different music styles and compositions. With a focus on the sound of the music rather than metadata like artist names, MusicLM offers a valuable resource for researchers, music enthusiasts, and AI developers looking to train language models on music-related data.
