This track is one of the two bonus tracks from Beat the Devil’s Tattoo. As seen on the reverse side of the album cover on this UK & Europe version, the title is actually supposed to be “1:51”:
Listening to a recording of the track, and reading the (rather miserable) lyrics hasn’t given much of clue as to what the title is supposed to mean though. It kinda looks like a time of some sort, and this line in the lyrics also alludes to time being significant:
The light is slipping away
But even if this is right, it could mean either a time of day or a duration of time;
- fifty-one minutes past one o’clock,
- one hour and fifty-one minutes, or
- one minute and fifty-one seconds.
Presumably, somewhere along the line, a piece of software has misidentified the track name as a number to process. And for whatever reason, it’s converted it from hours & minutes to days:
1:51 = 1 hour + 51 minutes
= 60 minutes + 51 minute
= 111 minutes ÷ (60 minutes/hour × 24 hours/day)
= 111 minutes ÷ 1440 minutes/day
= (37 ÷ 480) days
= 0.07708333… days
