A 2015 study of people's listening habits on Spotify found that most people stop listening to new music at age 33 and a 2018 report by Deezer found it be to at age 30. I have to say for years I kind of fell into this trap. I was into a lot of metal and hard rock as a youth and early adulthood and into my 30s that continued. I couldn't get into any new bands for some reason, It felt like I tried but just couldn't click with anything in my mid thirties. 

The catalyst was my divorce. It was hard, and ugly and a custody fight was involved. I found some of the stuff I was listening too became way too dark and depressing for the place I was in. It may help some people, but for me it just sent me even further down. 

It was during that time I started listening to Taylor Swift. Over time I started leaning more into pop music which did help my moods significantly. It turns out a lot of what was holding me back on trying out different genres was my fear of what people thought. I had this outdated view of manhood and masculinity and felt I needed to only listen to the hardest music or I was some how not manly or tough enough. I realized this was a silly thing to worry about. 
None of the people I was worried what they would think of me even bothered to check in on me during that time. Over the years, I started also getting into Sabrina Carpenter, Olivia Rodrigo and Dua Lipa among some of the bigger names. 
Tik Tok has given me access to a lot of indie artists of all genres, including metal, punk, and pop. Some I listen to more than others, but there are a lot of hidden gems out there if you are looking. 

My current fixation is Taylor Momsen and the Pretty Reckless. I disovered them a few years ago and excited to see their new album coming out soon and seeing them in concert in July. 

I know there is this propensity to say new music all sucks and new artists suck. But then we start soundling like our parents and grandparents when we were kids. I feel listening to newer stuff has actually helped me keep a younger mindset and has encouraged me to get out of the house more, even though I may be the oldest person at 52 at some events. Most people think its cool seeing older folks out and about having fun. 
When I got Pretty Reckless tickets, I could have seen them opening for AC/DC here in San Antonio or playing solo in Austin. I chose Austin. I used to love ACDC and still like some of their music, but I would have rather seen them in concert in the 90s when both them and me were younger. I saw Metallica in 1994 and it was an amazing show. I paid 20.00 for tickets. Pretty sure I wouldn't even be able to afford their tickets today and they are well into their 60s.  AC/DC is even older and not trying to be ageist, but I'm glad I saw Metallica in their prime. Though I know they still put on a good show, it just would feel different to me to see them now when I have such amazing memories of that 1994 show. 

I'm not trying to convince anyone of anything in particular. Just sharing my own experience. But I will say there is a lot of cool new music out there by some talented artists if we give them a chance.
