You don't need to eat up every musical product your fave produces like it's the next Bohemian Rhapsody.
It's totally okay to not fancy a song by your ult group because when the day is almost over, nothing they're gonna make is going to be perfect. Sure, some groups do make some quality products and you can like them all you want, but it's unrealistic to always be loving and gushing over everything your fave puts out. Critisism is always available when it comes to everything and it's very healthy for your brain to look at things on a critical level. For instance, let's say BTS put out a song and though you like it, you find some problems with it. That doesn't make the song bad, it's just unrealistic for the song to be perfect.
To sum everything up:
If you think a song is good then you may go ahead and like it, but pretending it's the best thing ever is faulty on it's own. A song can be good or even amazing, but it can always improve and critisism should be normalised.
Thank you everyone.
