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**”: [![The reverse side of a UK & Europe version of Beat the Devil’s Tattoo, showing the same thirteen tracks as the above image, but with two bonus tracks including “1:51”.][1]][2] <!--- UNNECESSARY (and irrelevant?) DETAIL But, often bonus tracks aren’t mentioned on the album cover, as seen in this US version: [![The reverse side of a US version of Beat the Devil’s Tattoo, showing only thirteen tracks.][3]][4] ---> 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 [1]: https://i.sstatic.net/Bu5ux1zum.jpg [2]: https://www.discogs.com/release/2182960-Black-Rebel-Motorcycle-Club-Beat-The-Devils-Tattoo/image/SW1hZ2U6ODE1NTk3NTc= [3]: https://i.sstatic.net/6xK1IuBMm.jpg [4]: https://www.discogs.com/release/2183121-Black-Rebel-Motorcycle-Club-Beat-The-Devils-Tattoo/image/SW1hZ2U6NDI1MjU2MjY=
