Listening to your own music library in the car

Dead spots on the motorway, a data allowance you would rather spend elsewhere, and a streaming app that stops mid-chorus at the tunnel. Music files on the phone solve all three.

Why streaming is the wrong tool at 70 mph

A car is the worst environment a streaming app has to work in. Coverage drops in cuttings, tunnels, multi-storey car parks and most of the countryside; handover between masts stutters at speed; and a long drive on mobile data is a real slice of a monthly allowance. Offline downloads help, until the one album you wanted is the one that did not sync.

The other half of the problem is attention. Fiddling with a phone while driving is both dangerous and, in most places, illegal — so whatever plays needs to be set going before you move, and controllable from the wheel or the head unit after that.

Files on the phone answer both. There is nothing to fetch, so there is nothing to stall; and once playback has started, the car’s own controls drive it through the standard iOS media controls that every player uses.

Step by step

Setting up a drive

  1. 01

    Put the albums you want on the phone

    Install bMusic and send music over from your computer with Import from Wi-Fi: open the address the phone shows, read the code with the camera, drag the folders in. A long drive is a good excuse to bring the whole of something rather than the singles.

  2. 02

    Build a playlist before you set off

    Drag songs into a playlist, or use a Tag to group whole albums for a trip. Doing it stationary is the point — the aim is that nothing needs touching once the car is moving.

  3. 03

    Connect the way your car connects

    Bluetooth pairs to the phone and shows track details on most head units. A USB cable or the aux socket both work as well, and a cable keeps the phone charged, which a five-hour drive will want.

  4. 04

    Start it, then use the car’s controls

    bMusic plays through the standard iOS media controls, so the steering-wheel buttons, the head unit’s skip and pause, and the lock screen all drive it. Siri and Shortcuts work too.

  5. 05

    Forget about signal for the rest of the drive

    Nothing is being fetched, so nothing can stall. Aeroplane mode changes nothing about playback, and the phone uses noticeably less battery with the radio idle than it does streaming.

Set the queue before you drive and keep your hands on the wheel. Whatever the law where you are, a playlist chosen at a standstill is the only safe kind.

Why files win in a car

No signal needed at all
Tunnels, cuttings, underground car parks and empty motorway between towns. Playback does not know or care whether the phone has a bar.
No data used
A five-hour drive costs nothing from your allowance, and roaming abroad costs nothing either.
Gapless where it matters
A live album or a continuous mix plays without the silence a track boundary usually inserts — the difference is much more obvious in a car than on headphones.
It resumes where you left it
Get out for fuel, come back, and the album picks up where it stopped rather than restarting or losing its place.

FAQ

Music in the car: the usual questions

Does it work over Bluetooth?
Yes. The phone pairs to the car as it does for any audio app, and most head units show the track and artist and let you skip from the wheel.
What about USB or the aux socket?
Both work. A USB connection keeps the phone charged on a long drive, and an aux cable avoids the Bluetooth re-encode entirely, which is worth having if the car has a decent system.
Does playing music use mobile data?
No. The files are on the phone, so nothing is fetched while you drive. The one thing that ever touches the network is a feature you have asked for, such as fetching lyrics.
Is there CarPlay support?
Yes, on any CarPlay head unit. Plug the phone in and bMusic is on the car screen with your own library — albums, tags and playlists, pinned tags first — and starting anything opens Now Playing, where shuffle, repeat, Like and the Up Next queue are all one tap away. Bluetooth, USB and aux still work exactly as before.
Will it drain the battery on a long drive?
Less than streaming does, because the mobile radio is idle. If you are driving for hours, plug in — that also gives you the USB audio route.

Lyrics for your own files

Lyrics apps look a song up in a catalogue. The rip, the bootleg and the demo are not in it — so the words have to come from the recording.
