I like the hourly music, but they should have gave us an option to turn it off. There was a period that I would play at 7PM every day after getting off work, and that song specifically was ruined for me because of how often I heard it. Now I just play the game at a low volume and play my own music externally if I'm decorating outside.
I know it's like that in every game, but it's not a hard feature to implement. At least I never really got sick of New Leaf's music, but I didn't play that game to death like I did with New Horizons. Heck, I'll even listen to hourly music from the GameCube and City Folk versions if there was a way to replace the songs.
