The answer to this question is dependable on what we define mainstream music as.
To me, mainstream can be regarded as something that appeals to the masses and lacks substance. For example in terms of music, anything that is charting on the top 40 or billboard 200 can be considered as mainstream.
I fid that we are currently living in a society that promotes the replication of others, which evidently makes it increasingly difficult to find some form of individuality. This, I believe is also taking place in the world of music. So many artists have a similar sound and image. We have it ingrained in us that one size fits all, it’s easier to fit into the mould of someone else who has achieved success and try to emulate that, as opposed to creating our own moulds that have yet to be proven viable.
Bringing it back to music now, yes the standardised, generic, carbon copied beat is catchy, but do the words have any meaning? Do they resonate with the audience in any type of way? 9/10 the answer is no, yet they still get air time and break streaming records. I think the reason behind this is because it so easy to passively consume this type of generic music. Sometimes the silence is so uncomfortable that we need to to fill it with something no matter the content. It’s easier to have something playing in the background that we don’t need to pay attention to, rather than listening to something engaging and thought provoking whilst trying to get on with our daily tasks.
