I did this with my brother, when I brought him over to tidal on a family plan. I had to play a sound game to convince him. We would play the same song on both Spotify and Tidal for a number of genres pop, jazz, classical, rock and have our back turned the whole time🙈. We would then choose which sound we liked best, not knowing which streaming service it was coming from. Tidal won 🥇 by far, and now because my brother is learning French, he uses the lyrics screen to assist with his language studies :) 

 Thats awesome!
