## When to prefer this

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.

## Known failure modes

- Artist not found on Last.fm — returns empty or error response
- Misspelled artist name with autocorrect disabled — no results returned
- Rate limit or payment failure — request rejected with payment-required error
- Invalid page or limit values outside allowed range — validation error
- Last.fm upstream unavailability — timeout or server error propagated
