Music downloads, MP3, iPods and CD music in the 50s

Music downloads, MP3 players, iPods, Walkman and CD music in the fifties and 60s.
There weren't any. None.
What we had were records made of vinyl which needed to be played on a record player (it was a while before there were record decks and turntables as separate things). A record player had a lid to lift revealing a round thing (the turntable) which went round; the record player was switched on, probably by the same small knob as controlled the volume, the record was placed on the turntable, the turntable switched on and the arm, which had a record needle in it, was carefully lowered on to the the outer edge of the record (disc). The music then started and, at the end of the record - which probably lasted a couple of minutes - the arm either stayed in the middle of the record or alternatively, if it was a posh player, the arm automatically came back to its rest.
At the start of the 50s, records were called 78s, because they spun round at 78 revolutions per minute (rpm). The records were 12" diameter (that's about 300 mm) and scratched or broke easily. They were quite heavy.
Towards the end of the 50s an exciting development was the 45 rpm record - this was only 7" across and was far harder to break (although it still scratched); it weighted a lot less and often came in a coloured printed wrapper - sleeve - where more about the record and its performer could be read.  On its heels, came the EP (extended play) which might well have 2 tracks per side - wow!
Of course, as many discovered, a 45 could not be played on a 78 player and new players (some even had radiograms) had to be bought.  These new machines could be adjusted to play at 78, 45 or 33 rpm; the 33 rpm was a 12" LP (long-play) record which might have up to 20 different tracks on it.
Some players had auto record changers allowing up to eight 45s or EPs to be loaded. Some earlier 78 only players had bamboo (yes, you read correctly) needles
