A copied tracklist can tell me what somebody typed. It cannot tell me whether the record exists under that spelling, which version played, whether the link still works, or where the artist actually sells it.
DJ Playprint starts with a DJ name and follows the evidence until it reaches a recording. Every useful result needs a chain that can survive inspection.

Current proof / four evidence cards
Four DJs, Four Source Conditions
Checked July 21, 2026
Batu and Four Tet are working profile artifacts. Seth Troxler and Carl Craig are corpus-level stress tests whose dedicated interfaces have not been run. Each card keeps that status visible, then opens into the source receipt and boundary behind it.

Batu
Identifier-rich baseline
Batu’s solo-primary NTS episodes provide unusually strong track-level identifiers. That made the first profile a clean test of exact recording matches without mixing in B2B or guest selections.

Four Tet
Coverage-rich portability smoke
Four Tet produced more documented sets and far fewer stable recording identities. MixesDB supplied breadth; NTS supplied authority; the profile kept the gap between a typed track string and a verified recording visible.

Seth Troxler
Volume-rich, attribution-heavy
Troxler has the largest set trail in the research corpus and the dirtiest text. Merged lines, inconsistent dashes, and a heavy B2B history make source attribution the hard problem before recording resolution even begins.

Carl Craig
Deep-history alias test
Craig supplies the deepest archive and the cleanest released-record coverage in the original stress test. The problem moves from finding track strings to preserving versions and linking aliases without erasing the credited artist.

The Sources Are Unequal
The research spikes tested Batu, Four Tet, Seth Troxler, and Carl Craig across radio archives, community databases, and music catalogs. The result was not one universal scraper. It was a source hierarchy.
Authoritative structured lane
NTS Radio
Public endpoints preserve source-owned episode and track data. Batu is identifier-rich; Four Tet shows how sparse the same lane can be.
Supported discovery lanes
Mixcloud, BBC, independent radio
Official APIs or parseable public pages can extend coverage, but every adapter needs its own terms and attribution review.
Community leads
MixesDB and 1001Tracklists
Useful for discovery and corroboration. They do not become authoritative simply because the tracklist looks complete.
Excluded from automation
Resident Advisor
Technically extractable, but outside the production ingestion boundary under the current terms and robots policy.
Rinse remains useful as a recording node, but the sampled episode pages did not carry populated tracklists. Audio recognition may eventually fill some gaps. It stays outside the first product because it changes the cost, rights, and confidence model all at once.
A Link Is Not a Match
NTS supplied 84 unique Deezer catalog IDs in the Batu corpus. A current API audit found 59 readable records and 25 catalog records that were not readable from this region. Eighty-two API ISRCs matched the NTS ISRC. The 50-record pilot admits a track only when the destination is readable now and the ISRC matches exactly.
Set evidence→Exact recording→Release evidence→Checked destination
Ploy’s “Ramos” is the first complete cross-archive receipt: set evidence, exact recording, official listening page, Discogs release evidence, and direct Bandcamp purchase. Other retailer buttons remain labeled searches until the release and version are verified. Three literal unknown-ID rows remain open. I did not guess them away.
What Broke During the Proof
Failure / 01
The research table widened the phone page
The table initially forced horizontal overflow across the whole document. It now scrolls inside its own container while the page remains at viewport width.
Failure / 02
Navigation landed below the wrong thing
Selecting a tool on mobile opened its content beneath the discovery hero. The interface now moves the chosen workspace into view before the person has to hunt for it.
The Batu and Four Tet profiles passed dedicated integrity, link, desktop, and mobile checks after their repairs. Seth and Carl remain corpus receipts until the same artifact gate runs for them. The distinction stays visible.
From Batu to Any DJ
Two profile runs prove that the pipeline can operate under unlike source conditions. Two additional corpus receipts expose the next hard cases before the interface claims to solve them. Seth forces collaborative attribution and dirty-line handling. Carl forces alias and version resolution across three decades. The general product should search on demand rather than copy the entire DJ internet into one brittle database. A cache hit can return existing evidence immediately. A cache miss can resolve identity, discover supported set sources, run the appropriate adapters, normalize tracks, and preserve every source URL and checked date.
01
Matched
One identity, source-backed sets, and a music list with visible evidence and checked destinations.
02
Ambiguous
Several artists share the name or alias. The person searching chooses the identity before extraction continues.
03
Sparse
Recordings or leads exist, but no reliable tracklist has been found yet. The gap stays visible.
