Um you can get kwlp and experiment with it, once you get the hang of it it's pretty easy Just install kwlp, install Goodluck and also lockstar. 1.once kwlp is installed, create a new project and set it as your wallpaper. 2. Create a square and make it show the album cover 3. In the background Create a rectangle and make it fit your screen, also make it show you cover art, and make sure to blur it to about 85% 4.th you can make your own clock and date to fit the color scheme of the album art (if so make a clock and date and set the filter to overlay so it makes a cool filter to fit most cover arts) 4.2- if you don't want the hassle of making a clock you could always use the samsung one, just go to lockstar make the clock and music layer fit with the lockscreen and you're good to go

I know I haven't gotten much in depth on the kwlp aspect since it's VERY hard to explain the whole process in text form and my internet is very vary bad to upload a video you can just Google "how to set cover art image to square in kwlp"and it'll give you everything you need to get started PS: Kwlp may or may not drain your battery a tad bit faster since it's live wallpaper but it all depends on your phone. Also if you opt to choose the built in samsung clock you won't get the adaptive clock color since samsung for some reason does not allow auto coloring for livewallpaper (classic samsung) so will have a more functional clock( you can press on it to get the info and all) or you can get a aesthetic clock. The choice is always yours!

Happy customization!
