What I listen to when writing depends on what I'm writing and how focused I am that particular day. I have a giant generic "writing" playlist on Spotify filled with instrumental music (mostly movie soundtracks) that I use for scenes where I don't really need tailored background music and for plotting. I also make a Spotify playlist for each WIP filled with songs that fit the mood. WIP-specific playlists tend to have lyrics, so if I feel like I'm going to get distracted and sing along I use the main "writing" playlist instead of the playlist made for whatever I'm working on.
