What this planner works out
This planner compares a journey's length against a playlist's, showing how many times the playlist would repeat and how much more music would avoid any repetition.
It is the lightest tool on the site and makes no claim otherwise. It answers a real question that people otherwise guess at badly.

Before you build a playlist
- Use total journey time including breaks, not driving time — the music plays at the services too.
- For a return trip, double it or build two playlists.
- Download rather than stream. Mobile coverage on rural and motorway routes is patchier than expected.
- Podcasts and audiobooks fill time differently — a single long piece removes the repetition question entirely.
A playlist that works for one driver for four hours rarely works for a car of four people. Shared control — everyone contributes a section, or a rotating turn — is the usual solution, and building it in advance avoids the negotiation happening at 70 mph.
How this calculator works
A ratio and a difference:
Journey minutes = journey hours × 60
Repeats = journey minutes ÷ playlist minutes
Extra music needed = journey minutes − playlist minutesThe repeat figure is deliberately shown to two decimal places, because the fraction is the informative part — 2.84 repeats means the playlist ends more than three quarters of the way through its third pass, which is where the repetition becomes noticeable.
Worked example: a four and a half hour drive
Using the default figures — a 4.5 hour journey and a 95 minute playlist:
- Journey length: 270 minutes
- Playlist repeats: 2.84 times
- Extra music for no repeats: 175 minutes
Nearly three passes through the same 95 minutes. Adding 175 minutes — around 45 more tracks — covers the journey without repetition. For a return trip it is 445 minutes of extra music, at which point an audiobook or a few podcast episodes is usually the more practical answer.
Common mistakes
- Using driving time rather than total journey time. Breaks and delays need covering too.
- Building for one way only. The return journey is the same length.
- Relying on streaming. Coverage gaps are common on long routes.
- Ignoring the passengers. A four hour playlist is a shared decision.
- Letting the driver operate it while moving. A passenger should handle music, or set it before departure.
Frequently asked questions
Should I use a playlist or an audiobook?
For a long solo drive, spoken word holds attention better for many people and removes the repetition problem entirely. For a car with passengers of different tastes, music is usually easier. Some drivers find audiobooks too absorbing on unfamiliar roads, which is a reasonable thing to notice about yourself and act on.
Is it legal to change music while driving?
Touching a handheld phone while driving is illegal in the UK, including to change a track, with a fixed penalty of six points and a fine. Using steering wheel controls or a properly mounted device with voice control is permitted. Setting everything up before moving off is the simplest way to stay on the right side of it.
How much data does streaming use?
Roughly 70 to 150 MB an hour depending on quality — modest compared with video, but a long trip adds up and it depends on continuous coverage. Downloading over Wi-Fi beforehand avoids both the data and the dropouts. The Mobile Data Calculator gives a fuller picture.
Does music affect driving?
Research findings are mixed. Moderate familiar music appears to help maintain alertness on monotonous routes; very loud or highly demanding audio can reduce hazard perception. Neither substitutes for a proper break — music postpones the sensation of tiredness without addressing it.
