"One man's trash is another man's treasure" is a phrase usually not associated with music choice however it is a true statement. Many music listeners would say they have a balanced music choice where they dabble in each genre because of a specific artist or song. Music appreciation is based on perspective, what may be moving to one person could have no emotional weighing on someone else. Music is all about perspective and what you make it out to be. So, can one call another's music choice "trash" if they don't like that genre or artist? Yes, but everybody has an opinion.
I pride myself on my music choice for its expansiveness and openness to new sounds and style. From country to metal there is something for everyone to enjoy in my play list. This appreciation for all genre types has allowed me to connect with many different types of people. Music is a conversation starter with anyone because it encompasses so much of our day. You cannot go a day without hearing some form of music. Whether it be a commercial, your car, or many other places, music follows.
Many close themselves off to whole genres because of social pressures or because they don't want to try something new, but what if we all were more accepting of this new experience? What if we tried something new on the ears? Stepping outside of your "musical comfort zone" is what I am saying. Listening to that one song you always skip or trying out that new band your friend keeps pestering you about. I am not saying that it will work out very time and you will enjoy the music, but it is all about trial and error. In the end that is how you find music you like, by trying it out and seeing if you like it.
I am understanding and rational enough to agree that not all music is good there are duds even from the bet artists. Some songs fall flat and are uninspired while others should not have been made all together. This however should not be grounds to call an artist "trash" because what they make is their art and can be appreciated by someone. Artists put a lot of effort into getting studio time and to produce the music. It may not be good but empathizing with them and respecting their talents is how the industry becomes better. Constructive criticism is always the route to go.
Music has a wide variety of genres and artists to discover and enjoy. As listeners we must be open to what it is trying to tell us and where it wants to take us. Being open to it makes listening more pleasurable.
