Styling music gallery

Hello. I could use some help styling a music gallery that I’m building.

Specifically, I’m trying to figure out how to use a Flexbox were the flex items form a column and as centered left-to-right. (I supposed I could use other mean, but it seems like Flexbox is the silver bullet to web design, so I wanted to try using it.)

In addition, I would appreciate any advice you can offer as far as how to make this simple music gallery/playlist look a little nicer.

Attached is what I have so far…
