As a worship leader and musician, my habit is to read a Psalm every day as a part of my daily Bible reading. As a result, I have read through the whole book of Psalms twice each year for the last 30+ years. I love to see the lament and praise that the authors of the book include in their prayers and lyrics.
I recently came across a great video that gives an excellent overview of the Book of Psalms. The video shows how the book is laid out and the different themes it presents. If you love the Psalms as much as I do, you will totally appreciate this excellent insight and information.
