Just like @rediaz I also like to look at lyrics while listening to music, so I made a custom theme with horizontal style inspired by his shared one (see A player that shows lyrics).
If you like my theme or have any suggestions please make me know by leaving a like or comment 
Excellent theme. I'm a new user of the Symfonium app. How do I download this theme? Thank you in advance for your attention.

Thanks for replying. I did your guidance, but the blur effect is not applied. I don’t know how to solve this.
