i won't even attempt to suggest that what works for me is what everyone else should copy. but this is just me.
music is a huge part of my life, and and i have had a difficult time finding what is right for me. while i was a christian for many years, i would say that of what i listened to, 99 percent secular and 1 percent christian. several years ago, i went through a bit of a crisis, in my personal life and spiritually, and you might say, redefined and rededicated myself to him. and on the other side of that, i realized that i was denying a conviction that i needed to be obedient in, so things needed to change. i was also denying that i could actually listen to some of the music i enjoyed and not be negatively impacted by it, if even subtly.
first off, the proportions changed a great deal, and much of what WAS acceptable in the secular realm went out the window. prayer and listening for His guidance, also seeking His word is how i found that balance for me, and as a result, sometimes i hardly listen to any secular music, but at other times, i listen to about 1/4 - 1/3 secular, and 3/4 - 2/3 christian music.
also, there is a lot of music that i am very attracted to, but just isn't ok for me to listen to. what also helped me to resolve the issue is a developed a test that i would give myself to help ascertain whether it was ok for me:
if jesus christ was sitting next to me in this chair, would i still be listening to this?
if a non christian friend was sitting next to me, would i still be listening to this (because i would be concerned about my testimony)?
does this music drive me, lead me, encourage me to do or think thinks that aren't christ-like?
this may be a horrible example, but i think of my christian music like i think of my regular, every diet of food. i try to eat mostly what promotes my health and well being. i think of my secular music as the food that doesn't necessarily promote health, but doesn't cause me a health crisis, like a brownie.
the stuff that i referr to as "pleasant, enjoyable, fun, but not ok for me because i don't want those messages and thoughts marinating in my brain, popping up in my thoughts or contributing/creating of insensitivity in my life about certain topics or things" -- i just have to avoid. i think of it as the same thing as adding a few ounces of antifreeze to my water bottle. i doesn't kill you immediately, but it sure messes you up for awhile and a steady diet of such WOULD kill you. i try to listen to that conviction and just leave it out.
also, i should point out that some of the stuff i used to listen to that was in the "ok" secular music category, i have later been convicted about it, and avoid it now.
finally, i also try to avoid listening to radio stations in which i will hear lots of new, questionable music, as it just creates more problems for me. i tend to listen to a lot of songza-type apps/sites that allow me to choose genres, or create my own playlists, and listen to christian radio stations. full that the secular music i do listen to doesn't corrupt or take away from my spiritual walk or mindset, the opposite is true about christian music. it effortlessly puts scripture in my head, worshipful notions in my heart and mind, and helps me to
"...whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things." phil 4:8
hope that helps.
