I would definitely choose Spotify! I like the look, very simple and quite elegant. The user interface is intuitive and easy to navigate, making it a pleasant experience to browse through my favorite songs and playlists. However, if it's not premium, you won't be able to enjoy the features such as offline listening and ad-free music. On the other hand, YouTube music offers a more complete music library with a wide range of songs and artists to choose from. It also has the advantage of integrating seamlessly with other Google services. Ultimately, it all comes down to personal preference and what features are most important to you. But for me, Spotify takes the cake for its sleek design and user-friendly platform.

In conclusion, while all three options have their own unique strengths, Spotify stands out to me as the top choice. Its simplicity and elegance make it a joy to use, and the premium features are well worth the investment for a truly seamless music listening experience. However, it's important to consider your own music preferences and needs before making a decision. Whether it's Spotify, Apple Music, or YouTube Music, each platform has something special to offer. But for me, Spotify's sleek design and user-friendly interface make it the clear winner.
