We call a collection of recorded songs an ‘Album’ because 78rpm records only could only hold 3 minutes of sound per side. Selling a recording longer than that meant packaging a collection of disks in an album
So when ‘Long Player’ records came along the name ‘Album’ stuck.
‘Long Players’ typically hold approx 22 minutes per side with the exception of two copies of ‘The Golden Record’ each travelling on the two Voyager space probes. They contain field sound recordings (waves, wind, thunder) spoken greetings from people all around the world in 55 languages, an hour of music from navaho chants , symphonies, and Chuck Berry, various analogue encoded photos of the earth and the things and people on it and an hour of the recorded brainwaves of Ann Duryan falling in love.
Due to a piece of text being engraved on the disks being of the wrong specification the decision was almost made to just put blank disks on the space probes instead.
