Ask whether the new track reuses a performance, a composition or both
Ask what came from the old work. Did the artist reuse the song, copy old audio, play a part again or rebuild an old master?
A cover performs an existing song again.
A sample copies audio from an older recording.
An interpolation plays an old part again. A remix rebuilds recorded sound.
A cover creates a new recording of an existing song
A cover performs an existing composition again. The new artist may change key, tempo, arrangement, voice or even some wording, but the recognizable song remains the compositional source. The cover should have its own recording identity and usually its own recording code.
A lyric reference must follow the words actually performed. Do not paste the original transcription over a cover that omits a verse, changes pronouns or adds a spoken section. Composition credits may carry over while performers, producers, release and timing belong to the new recording.
A sample reuses recorded audio
Sampling takes a portion of an existing sound recording and places it in a new track. The reused material may be obvious, chopped, looped, filtered or pitched. Because the actual audio is reused, both the sound recording and the underlying composition can be relevant to permissions and credits.
Sampled vocals are not automatically the new track's lead lyrics. Transcribe audible words when authorized and useful, but identify their role and source. A repeated fragment may function as texture rather than a narrator continuing the new verses.
An interpolation re-performs earlier material
Interpolation recreates part of an earlier composition without copying the earlier recording. A singer may perform the old melody with new production, or an instrumentalist may replay a recognizable phrase. The result can sound like a sample even though the audio was newly recorded.
Credits help distinguish the relationship, but listen and compare reliable release information. An interpolation may change words while preserving melody, or preserve a lyric phrase with a new performance. Those choices affect what belongs on the new song's lyric page.
A remix reworks recorded material into another version
A remix uses elements from an existing recording and changes the mix, structure, tempo or production. It may add a featured verse or remove sections. Some releases called remixes are closer to new recordings, so the commercial label alone does not describe every technical choice.
Treat a remix as version-specific. Check duration, full artist credit and section order before reusing lyrics or timestamps. A new guest verse changes the text, and a rearranged drop can shift every later cue even if the lead vocal comes from the original recording.
Use credits and audible evidence together
Start by asking whether you hear the original performance or a new one. Then inspect songwriter, performer, producer and sample or interpolation credits. Databases can omit relationships, while listeners can mistake a skilled re-performance for copied audio. Agreement between documentation and sound makes the classification stronger.
These labels carry rights consequences, but a public lyric page should not make legal accusations from resemblance alone. State supported relationships, cite the release context and send disputed ownership claims through the appropriate rights process.
Classify what changed before comparing lyrics
These labels describe different relationships between a new recording and earlier material. More than one relationship can exist in the same track.
| Relationship | What usually carries over | Lyric-page implication |
|---|---|---|
| Cover | A new performance of an existing composition. | Treat it as a distinct recording; wording and arrangement may differ from the earlier performance. |
| Sample | Audio copied from an existing sound recording and used inside a new one. | Do not assume sampled words are a lead-vocal lyric; identify their audible role and source carefully. |
| Interpolation | A newly performed recreation of material from an earlier composition. | The sound recording is new even when melody or words deliberately recall the earlier song. |
| Remix | Existing recording material reworked with changes that may include production, sequence or new vocals. | Check featured credits, duration and added or removed lyric sections rather than reusing the original page blindly. |
What to do next: Use release credits and listening evidence together. A familiar hook does not by itself establish whether the track uses a sample, an interpolation, a cover or a remix.
Reuse terms that sound similar but are not interchangeable
These answers focus on what can be heard and what the credits can verify.
Is an interpolation a sample?
No. A sample copies existing recorded audio; an interpolation newly performs part of the earlier composition.
Is every new performance a cover?
Not necessarily. A short re-performed element inside a new song may be an interpolation rather than a cover of the complete composition.
Do remixes need separate synced lyrics?
They do when timing, section order, words or featured performances differ from the original recording.
