This really depends on what kind of mood I'm in. Having multiple playlist is essential for me. For articles and blogs I turn up my favorite radio station or playlist and listen to classic rock from the 60's, 70's and 90's. Mostly The Beatles, Clapton, and pop rock. When it comes to more personal writing such as on a book project or working manuscript than my taste change, pleasant lyrical songs from Coldplay or non-lyrical inspirational music will do too, even jazz. I even enjoy listening to just nature sounds, chimes, wind, ocean, and thunderous rainstorms. Having background music actually helps me to focus more and inspires me to write.
