What role does a distributor play in relation to record labels?

A distributor plays a vital role in bridging the gap between record labels and the consumers and retailers who purchase music. They are responsible for the logistics of getting music from the label into the hands of the public. This includes physical distribution of CDs and vinyl as well as digital distribution through platforms that sell or stream music. By linking the label to consumers and retailers, the distributor ensures that the music produced by the label is accessible to its audience, ultimately helping to drive sales and grow the label's market presence.

The other roles mentioned in the options do not accurately reflect the duties of a distributor. Creating apps for music consumption is typically within the realm of technology companies or developers rather than distributors. Hosting live concerts is generally the responsibility of promoters or venues, while writing songs is typically the domain of songwriters and artists themselves, not the distributor.
