Multi-dimensional spinning

This is one reason why I love spinning. It is soo multi-dimensional from the layers in the music to the possiblities for inspiration. The same profile/playlist can grow as you use it. First time it can have an introductory feel as the instructor and the students begin to catch onto the training objective. Sometimes the whole class will be over before you can practice with confidence the new skill introduced whether it is
a new way of looking at the pedal stroke you have never tried before or jumping to a quicker beat.The second class you can take your new found skills to a new level. The third class you are able to change the approach to one of a motivational ride that stems perhaps from things you have learned in your own life recently. Perhaps in the fourth class you have found the nuances in the song that promote that added pedal stroke or increased effort or slow build and you can really milk the music for all its worth. Talk about fun!
How do you reinvent your profile/ playlists?
