Audio Borrowing Rights

A 'Sample' lifts the actual master audio recording directly from an older song. An 'Interpolation' re-records the melody or lyric with new instruments from scratch.

Distribution Rules:Sampling requires clearance from BOTH the master recording owner (label) and the composition publisher. Interpolation only requires publishing permission.
Example: Olivia Rodrigo's '1 Step Forward, 3 Steps Back' interpolates Taylor Swift's 'New Year's Day'

From Vinyl Records to Streaming Badges: A Brief History

The Origins of EP and LP

In 1948, Columbia Records introduced the 33⅓ RPM microgroove vinyl disc, dubbed the Long Play (LP) because it could fit 22 minutes per side. Soon after, RCA introduced smaller 7-inch discs with 2 songs per side, dubbed Extended Play (EP).

Today, digital distributors still maintain strict track and duration rules to distinguish between singles, EPs, and full-length albums.

The Explicit Badge & Modern Streaming

Following the 1985 PMRC hearings, physical records received the black-and-white “Parental Advisory: Explicit Content” sticker. In the streaming era:

  • Distributors require artists to self-declare profanity
  • Failure to tag explicit songs can lead to platform removal
  • Clean versions allow airplay on commercial radio and school dances
