I like features like 'swap' (F5) to juggle songs within an hour, and also I like the 'artist history' dropdown option to study song history not just by title, but by artist as well. Another feature I use a lot is 'highlighting' songs (F7) so I can clearly see what I consider to be 'exclusive' or 'lesser familiar' songs to our format. If I see too many highlighted songs in an hour or clumped together, I can rethink that music sweep to maximize music discovery and our format's exclusive songs/artists, but still remain cume-friendly!
