No Kufr, but Avoid Harmful Content

I am afraid i have committed kufr by listening to these songs There is a series i enjoy which has multiple mediums (movies, books, videogames). It doesn't have an anti religious message or anything like that. The issue is that sometimes these pieces of media are accompanied by music. (I know music is haram and i try not to listen to it anymore) 2 of the songs that are part of these movies and games have questionable lyrics with one of them including bhudist chants and the other one having these lyrics which are supposed to show the how the bad guy is evil and what they think: "In your gods you seek guidance, forgiveness, salvation, and release. F**k that sh**, They're not here. Sick religions will find you no peace." These are very vulgar and questionable lyrics. Can i still enjoy the series if i avoid these? Also i did not realise out of my ignorance up until some time ago that i had been singing and muttering these songs without any thought, will i be held accountable for this?( I did not realise the severity of the act) Have i committed kufr by listening to these? Do i commit kufr by watching more of this series considering the songs?? I only recently realised that what i have been enjoying has these very questionable lyrics on some of their music. I know i should avoid these (and music in general) but would the other stuff be fine considering these songs were there to show a fantasy setting of an evil character. Please give me an answer if you can, i just found out that one of my favorite series may be kufr to me .
