> The Beatles wrote 227 songs, but only 34 hit the Top 10. Do you think they would put out a song that they didn't believe could be a hit? Mozart wrote over 600 songs, but only about 50 of them are widely played. Do you think he purposefully wrote duds? Of course not.

This is completely backwards. The Beatles put out songs that they didn't think were hits, and put out songs that they were conscious of being the antithesis of a hit. They wanted to freak people out from time to time. As many artists do.

Just check out Revolution 9. Pretty sure you can't get much out there than that when it comes to music of that era. And still very out there to this day.

Or for a more 'songy songs' that I'm pretty sure they didn't think at all in terms of hit material: Tomorrow Never Knows or Within You Without You. And there's dozens more.

Off topic but always incredible to remember the Beatles only recorded for what 7-8 years. Incredible what a legacy that is for such a short period of being a band

Writing a song is just the beginning. Then there is all the massive effort with the arrangements and polish for it (see George Martin). I doubt the Beatles would make the effort unless they thought a song was worth it.

In the days of the Beatles, and throughout the heyday of the recording industry, the artists and their management pursued "hits", to be sure, and wanted to be seen on the Billboard charts and in rotation on the radio. But that was secondary to sales figures.

It was the RIAA that certified sales figures and awarded the Gold Record, Platinum, and Double Platinum prizes. There were various formats that records could be distributed in, but let's simplify to the "album" and the "single".

A single was typically one song on each side, A/B, and the A-side was considered desirable and marketable. Singles were purchased first by radio and dance DJs so they could be played individually on demand. There was a secondary retail market for singles, so consumers could purchase them as well.

The record album developed from a set of many 78 discs and coalesced into a single, Long-Play, 33.33 RPM record. Its capacity was about 6 songs per side, depending on their length.

There were various strategies for collecting songs into an album, such as a sampler of the artist's best, all their performances in a year's sessions, or even various artists. During the Beatles' fame, the "Concept Album" and "Album-Oriented Radio" (AOR) came into being.

So you could sell singles with one hit song, and this would propel the "B-side" into people's homes as well, so they may get curious, flip it over, and play the B-side, but B-sides were often considered lower quality, disposable, or less popular.

An album could sell great if it had one hit track. Recording companies would usually peel off the best tracks on an album to release as singles too, so that the radio play would promote the band and drive sales of the entire album. Many people who heard a hit song would be disappointed when they spent a lot of money on an album, only to find "filler" in-between, because the album format usually guaranteed a certain runtime or number of tracks.

When the Beatles produced "Sgt. Pepper" it was a foray into the "concept album" where all the tracks contributed to a cohesive idea or theme. This tended to enhance album sales over singles, because the single would be a peek into the larger "concept" and whet the public appetite for the whole thing.

When "Album-Oriented Rock" became popular, the DJs were freed from the constraints of playing "hit singles" in isolation and they were more encouraged to explore the unreleased tracks ("deep cuts") from albums, as well as tracks of longer duration that weren't appropriate for hit radio stations. In turn, AOR bands were under less pressure to release their "hit single" for every album and shielded from the phenomenon of "one-hit wonders" while instead their audience was, again, encouraged to invest in an entire album.

In the 1980s, a 45 RPM single may cost $1.50 or $2, while a full-length album was $8.99 to $12. The format switch to cassettes was sort of masterful, because for a while, the 2-track single format was abandoned, and consumers were kind of forced to get the entire album on cassette.

Yes I've ignored a lot of rough edges here, like the older 78s, and 8-track cassettes, and classical radio, but that was basically the landscape for pop artists, who needed hits but first and foremost, needed sales. The Beatles also capitalized on another enduring method of driving record sales: live performances and world tours. It wasn't called "The British Invasion" for nothing.
