A lad I know was a regular in one of the pubs I used to frequent, which had a jukey the CD covers mapped in a 2x2 grid of a catalogue that rotated to show off what was in the box - generally 99 CD’s worth, likely a limitation of the input display than any software constraint.

Rather than scroll through the jukey CD’s, you could literally ask him a song and he’d give you the two digit CD number, and two digit track number. It was impressive.

Or, you could put two quid in for 12 tracks or whatever, put on two bangers, and the other ten stupidly long November Rain style songs, or Christmas songs in July, by which point you’d have finished your drink and fucked off because the “skip song” control behind the bar had been gubbed for years.

Fun times - and very specific to a twenty or thirty year window in time, too.
