I use a lot of music while writing. It really throws me into the right headspace needed for certain scenes. I thought I'd list some of the songs that are inspiring book 4 in case anyone is interested.
Poison by Alice Cooper
Unfaithful by Rhianna
Back to December by Taylor Swift
I Didn't Want to Need You by Heart
Secret by Heart
Blonde & Blue by The Headstones (The book is titled after this song which is by a Canadian band that I adore. Here's the youtube link if anyone wants to check it out: https://www.youtube.com/watch?v=x6BbTwUr5vo
Seize the Day by Avenged Sevenfold
Song From an American Movie by Everclear
Crimson and Clover by Joan Jett & the Blackhearts
Wasted Time by Skid Row
Already Gone by Kelly Clarkson
El Tango De Roxanne from Moulin Rouge
I'll leave the list like this for now and come back to add more as I go.
