The industry has changed a lot. It's really difficult for talented artists to get a huge following in the way they did before.
If you think about it, back in the mid 20th century, up until the 90s, you could have solo artists, or more often bands, get together, start writing songs, and they could get radio play and a record deal. The record company would invest some money in helping them develop and promoting them.
And they produced so much music, often had a full catalogue before they were 30.
Now you rarely see pop musicians with more than two albums in their 30s. And the number who write their own songs is quite small. No bands that developed somewhat organically, usually the "bands" are professional session or touring musicians the recording company hires. They also hire the songwriters.
The music tends to be very samey, and it also tends to be thin - the musicianship is lacking and a lot of the music backing is generated electronically.
There are great bands and musicians out there, touring and making a living, but they aren't on the pop charts.
