Does anyone else use music or anything like that for writing inspiration?
I do! I mostly write to instrumental music, as music with lyrics distracts me unless I'm really inspired.
I always listen to BSB when writing fanfic, because it puts me in a BSB mood. Over the years, it's become more and more "soundtrack to your life," so I can tune into the feeling without focusing on the lyrics as much. I've definitely used certain feeling beats for certain chapters. Ch. 14's fight was mostly written to the ambient sounds of DWYB on repeat over and over. Though certain songs definitely qualify as distractions when they pop up on shuffle. QPG, IAWLT, GAB, ALAYLM, Backstreet's Back come top of mind. Chances is always a distraction, but I walked down the aisle to it, so it's for multiple reasons (good song, wedding memories, feelings about my husband, feelings about the Boys, etcetera).
In ye olden days, I used to listen to NSYNC when writing Renee/NSYNC focused chapters, but haven't in the edit yet because the last day I edited chapters focused on them was my birthday and I just didn't want to listen to NSYNC on my birthday, ha. Might try it again for their next chunk though. See how far it gets...
I haven't tried any ambient moods playlists yet! If it's original fiction, I typically work in silence or the ambience of background TV noise.
