Sometimes you need to get into the right mood. Maybe your kids irritated you, and then you need to work, be creative, find a solution to a problem you’ve been working on etc. Music helps, and people have their own experiences and preferences as to what music does it for them.
Have an online repository, where you can create a playlist with what works for you for a given mood you want to get into. You can also check others’ lists and try them out when you need to get into a certain mood and you don’t have a playlist you can start with.
