Musicians with january birthdays: what to know and why

A musician's date of birth lives in more registries than almost anyone else's, and almost none of them are public. The bodies that pay royalties need to know exactly who a performer is, and they keep the data to do it. The sites that publish musicians' dates have no access to that data, so whatever they show came from somewhere less reliable.

What to take away

• Royalty systems hold identity data, including dates, for the purpose of paying the right person. That purpose does not extend to publication.
• Public music databases sit at the bottom of a chain whose top is closed to them.
• The identifier, not the date, is what ties a performer's records together, and it is the field a compiler should chase.

Who needs to know who a musician is

Royalties are paid to people, so every organization that collects and distributes them keeps a register of members detailed enough to tell two people with the same name apart. That is what an Interested Parties Information number is for: an identifier assigned to writers and publishers so that a work can be tied to the right person for payment. It exists because names are not unique and money has to land somewhere.

The International Standard Name Identifier does a similar job more broadly, for anyone who contributes to creative works, across libraries and rights systems. Neither identifier is a birth date. Both are what makes publishing one unnecessary: two records with the same identifier are the same person, whatever the name on the sleeve says.

What a public database actually holds

Source	What it knows well	Where its date came from
Rights society register	Identity for payment	The member's own application; not public
Library authority record	Names, variants, works	Reference sources, sometimes the person; may hold a year for disambiguation
Fan-maintained discography	Releases, credits, catalog numbers	Copied from press material or from other sites
Label press material	The career as the label wants it told	The artist or their management
Liner notes	Credits for one recording	Nothing about birth at all

The date on a fan-maintained site, which is where most public music dates sit, is at the bottom of this chain. The sources with real identity data are at the top, and they do not publish it.

Why a musician's public date is fragile

• Stage names. The name on the record is not the name on any document, so matching a performer to a civil record is guesswork unless an identifier bridges the two.
• Bands. A group has a formation date and its members have birth dates, and databases confuse the two fields regularly.
• Year-only values. Discographies care about release dates, so a performer's own date is often held to the year, and a rendering step turns that into a day, as the June page describes.
• Press biography. Where a public date exists it usually began as marketing copy, which had no duty to be right.

What a compiler should chase instead

The identifier. A performer with an ISNI, an IPI number or a library authority record can be tied to a body of work without any date at all, and the body of work is what makes them notable in the first place. The January index puts identity before date for every entry; for musicians that order is not merely correct but the only one that works. The famous-January page covers what the threshold for listing should be, and a threshold met by a body of work needs no date to apply.

Common questions

Can a rights society confirm a musician's birth date?

Not to the public, and it should not. It holds the date to pay the right person, and that purpose does not reach a birthday page.

Is a band's formation date a birthday?

It is an anniversary, and a useful one. It belongs in a different field from any member's birth date, and a database that puts both in one column will eventually swap them.

Why does a musician's entry here give a month and nothing finer?

Because the month is enough to place them on the page, and the February page explains why a fuller date is a key that does not belong in public.
