What counts as a single and why it matters for best sellers
When people ask for the best selling music single of all time, they usually want a definitive answer, but the reality requires clarification first. A music single is a recorded track or set released separately from an album, often formatted physically as vinyl or cassette, and digitally as downloads or streams. Because certifications, markets, and formats differ, reported numbers can vary. This evergreen explainer defines what qualifies, reviews the leading verified contenders, compares sales by source, and clarifies common confusions so you can rely on the context for long term usefulness.
Leading verified contenders for best selling single
Across major certification bodies and historical sales data, two titles appear most frequently at the top: Bing Crosby’s White Christmas and Band Aid’s Do They Know It’s Christmas. Both are holiday charity recordings with multi million unit reports. In some regions, Elton John’s Candle in the Wind 1997 also appears at the top, especially when measured by certified units in particular markets. None of these are recent releases, which reinforces their evergreen status and sustained catalog sales over streaming and physical reissues.
How sales figures are verified and reported
Because no single global database captures every transaction, best selling claims come from a mix of label reports, trade association certifications, and industry compilations. When evaluating numbers, prefer sources that disclose methodology and align with recognized certifiers. The following table summarizes commonly cited figures, units, and source types for the top candidates mentioned most often in authoritative records.
| Title | Metric (units) | Reported range or figure | Source type |
|---|---|---|---|
| White Christmas (Bing Crosby) | Units sold (physical & digital) | 30–50 million | Label and industry certifications |
| Do They Know It’s Christmas (Band Aid) | Units sold | 13–20 million | Label and charity reports |
| Candle in the Wind 1997 (Elton John) | Units sold (certified) | 12–20 million | Certification bodies |
Key definitions and boundary conditions
- Single vs album: Industry certifications may count one track as a single if sold separately or bundled in a way that tracks are individually purchasable.
- Physical versus digital: Early figures are based on shipments and sales; modern figures add paid downloads and streaming consumption converted to equivalent units.
- Charity compilations: Records like Band Aid are often treated separately in charts because proceeds benefit a cause and sales channels differ.
Regional differences and chart methodology
Not all charts count the same thing. Some focus on pure sales, others include streaming equivalent units, and rules about what qualifies as a single can vary by territory. A record may top one country’s list but appear lower in a broader aggregation. Always check whether a figure represents shipments, sales, or consumption-based equivalencies, because methodology changes over time and affects comparability.
Common confusions and how to avoid them
- Best selling single versus best selling song: If a song is part of an album and not purchased or streamed as a standalone track, it may not be classified as a single in certification terms.
- Streaming equivalencies: Platforms convert streams into album and single equivalents; these conversions are useful for charts but are not always directly comparable to historical unit sales.
- Reissues and repackaging: Later rereleases can inflate cumulative units, so reputable sources distinguish original sales from reissue bumps.
Practical takeaway
For an evergreen answer, treat Bing Crosby’s White Christmas as the most commonly cited best selling single, while noting that Band Aid’s Do They Know It’s Christmas and Elton John’s Candle in the Wind 1997 are also plausible depending on market and methodology. Base your understanding on verified certifications, transparent source descriptions, and clear definitions of what counts as a single, rather than on headline figures that omit scope and context.
