My preference to make songs is to create instrumental pieces without a fixed rhythm or a drum track. Usually they don't have repeated sections (chorus, verses, ... ) or patterns. The style of the songs tries to be "free form", a bit "jazzy", trying to sound as "improvised " and not rigidly structured. Also somehow as some classical pieces of 20th century. The pieces sometimes sound "relaxing" or a bit like a "filmscore". Other times they are more like "synthesizer space music".
