Any genre of music is all about the singles at the end of the day. Even if your entire album holds together as a full experience, you always need that one song to hook the listener in from the beginning. Sometimes it comes down to the catchiness or the subject matter, but a lot of songs with massive potential have been left on the cutting room floor.
Throughout rock's glory years, there are many bands who could have had huge hits if they had just released these as singles, but because of label issues, creative differences, or just indifference, they were never brought to the public. They may have never been given the same treatment as their fellow album tracks, but these songs have taken on a life of their own as of late. Since they never saw the light of day, a lot of these remain fan favorites and have even become staples in the band's live catalog because of how much they resonated with fans.
Even if they aren't released proper, some of things ended up clicking with audiences so much that they end up getting played on streaming services more often than the actual singles. They may have had a slow start, but the shelf life behind these tunes has been extremely kind.
I'm just a junkie for all things media. Whether it's music, movies, TV, or just other reviews, I absolutely adore this stuff. But music was my first love, and I love having the opportunity to share it with you good people.
