About Tunestats

Apple Music and Deezer both publish a daily chart. Neither keeps it. Tomorrow's chart replaces today's, and the shape of a song's run — how fast it climbed, where it stalled, how long it held — is simply gone.

Tunestats captures both charts every day and keeps them. That is the whole idea. The archive is the product, and it gets more useful every day it runs.

Where the data comes from

• Apple Music — the official Marketing Tools RSS feed, published by Apple, updated daily, one feed per country.
• Deezer — the public Deezer API chart endpoint.

Both are public and unauthenticated. We capture once a day and cache aggressively, so we stay a light consumer of feeds we do not pay for.

What we don't claim

• These are platform charts, not sales charts. They are not Billboard, the Official Charts Company, or any certified national chart.
• History starts when we started. A song that peaked before our first capture shows its peak as we recorded it, not its true peak.
• Cross-platform matching is done by normalising titles and artists. It is good, not perfect — a remix credited very differently on two platforms may show as two tracks.
• Deezer's public chart endpoint is not country-scoped, so it is shown as one global board rather than split into countries it did not give us.
