StableMusic Similar Tracks by Artist

Use this endpoint when you need track-level music recommendations similar to a specific artist, leveraging Last.fm's established similarity graph. Prefer this over generic music search endpoints when the user already knows an artist and wants sonically or stylistically related tracks. Best for music discovery flows, playlist generation, or recommendation engines.
