Spotify web player changing songs

[Melldoza]

Everytime I use spotify on my phone and listen to music from my liked playlist, spotify will then stop the song that i'm listening to and change my song to a random song that I dont know. This only happens when its tells me that I am listening to spotify web player and it will ask if i should continue on my iphone or web player. Either way I find it annoying when it changes what i'm listening to randomly and I want it to stop doing that because its really annoying, especially when Im listening to a song while driving. Does anyone know how to fix this?
