Looking back at what I listened too in 2019 it appears the random algorithm in my music player has a large bias to the Del Vikings.
More representative The Motors make the top five tracks with a pukka pop song.
But op of the tracks was from a little more recently: Frog by ハイスピード瞬き.
Trying to sort out anything else is somewhat thwarted by the bands with the most releases coming high up by law of averages. And having combined the entire Django Rheinhardt Chronolgoical series into one album of 300 tunes blots out all other contenders.
I’m hanging on a bit for the best of this year’s releases as I wouldn’t want to be caught out by any late comers.
