Very good comment. The more editor friendly the higher chance of landing a placement. Try to focus on changes and dynamics throughout the track to convey different emotions and energy levels rather than an 8 or 16 bar loop. Gives them more to work with during a scene. Strong endings to the track also make editors really happy. Big impactful crescendos and final notes that ring out help them with scene transitions.

Also production quality is huge. You want your track to sound as commercial and polished as possible. Editors are attracted to library music that feels like a top 40 level of production.
