The papers said Ed always played from the heart
He got an agent and a roadie named Bart
They made a record and it went in the chart
The sky was the limit
His leather jacket had chains that would jingle
They both met movie stars, partied and mingled
Their A&R man said, "I don't hear a single"
The future was wide open
(Tom Petty - "Into the Great Wide Open")
Wiki: Artists and repertoire (A&R) is the division of a record label or music publishing company that is responsible for talent scouting and overseeing the artistic development of recording artists and songwriters. ....
The record companies pick the songs to push and payola for. Independent artists do the same when choosing the 1-2 songs to play for appearances on shows, podcasts, radio stations, etc. and which ones to make a YouTube video for.
But sometimes the listeners pick their own songs to make a surprise hit. Or at least they used to in ye olden times of vinyl and CDs.
And once in a blue moon a movie or TV show will decide to use a "deep cut" from an album and make it a hit that way. House M.D. using Massive Attack's "Teardrop" and Wild At Heart using Chris Isaak's "Wicked Game" come to mind.
