In the USA I subscribe to Youtube Premium family. The rate is just $3.00 a month more than Spotify family. For that price you get both the Spotify-equivalent Google-owned service (confusingly called YouTube Music) AND you get ad-free Youtube as a bundle. Basically just $3/month for no ads on Youtube is worth it and much easier to justify for a household on a tight budget.
It might be worth looking into if the pricing differential is similarly minimal where you live.
