If I delete the "Music" app on my phone, will the songs still be on my laptop?

Even though this may not be great to say on the apple website, I rarely use the designated "Music" app that comes with an iPhone and have been exclusively using Spotify. When I made the switch I kept the songs in my library because some I do not want to delete, but overtime it has become a trend where I am almost always using about 95% of the phone's storage, so I am debating just deleting the app from the phone considering that is now an option. That being said, I do not want to delete my entire music library in case I ever want those songs again **(none of these songs are on Apple Music because I have never used that. All were purchased or downloaded as mp3 files)**. Which brings me to my question: If I do end up deleting the music app from my phone, will my entire music library be deleted with it, or will they still accessible in the iTunes on my MacBook?
