I say this because I am actually knowledgeable about game making, I am not someone who talks about things they are clueless about, you underestimate me and it is not as hard to find commercially usable musics as you make it sound, you can simply read other adult games' credits to know where they got their musics from and I can even share some sources which I found myself with you:
Incompetech (the most popular composer of royalty-free-for-any-use musics who is even open to custom requests)
AudionautiX (the second most popular composer of royalty-free-for-any-use musics)
OpenGameArt.org (one of the most popular free open libraries of resources for games including countless graphics, musics and sound effects)
Free Music Archive (one more library of free musics)
And about sound effects, I can also share more than OpenGameArts which I already did but I know some other libraries of free sound effects such as:
Freesound (the most popular library of free sound effects)
Sound Fishing (a french library of free-for-any-use sound effects)
See? This is not that hard to find some free-for-any-use resources and you don't lack choice already with the countless resources from each one of these few libraries.
You can state that you made playlists by themes as much as you want but it will not change the fact that I turned off your musics because they break the mood, what more do you need to conclude this doesn't work as well as you hoped?
I see, what you basically mean is that you have to include musics for many scenes at once instead of having included musics from the start as you developed your game, fair enough but this was your choice to ignore musics up until now.
You basically state that you dislike musics in games which makes it to be expected that you are not proficient at including musics into your own game.
You answered to a comment which I made 3 months ago about your game so you know well that I don't think your game is crap and, honestly, if I thought your game is worthless then I wouldn't waste any more of my time with it not even to criticize it if I was convinced it was hopeless.
You are the one who took my opinion to heart and defend yourself as if you are on trial then claim you are not, you put yourself on trial though, I didn't do it, then you claim this is my issue even though this is obviously yours from your disproportionate reaction.
Honestly, I appreciate that you answer to comments and communicate with your players, however don't lash out at me out of a point of view which I shared instead of explaining if there is a misunderstanding, you could have simply explain that as a player you use to turn off musics in games which is why you don't know how to proficiently choose musics for your own game, and actually, you could even choose to not include musics into your game since it is actually more enjoyable without the musics which you included which, as I repeatedly stated, break the mood instead of enhancing it so I muted them anyway, and I commented 3 months ago how much I enjoyed your game even before it included musics so if you actually don't know how to choose musics then you might as well not do it and focus on what you know how to do. 😉
And if you really want to satisfy players who need musics to enhance the mood then instead of wondering which musics would fit your game, just listen to musics until you hear some which actually inspire you and remind you of your game and then they are musics fitting your game. 😉
