Many of these audio tracks can be extended to be arbitrarily long. It would be great if there were longer versions that could simply be trimmed in Camtasia. I'd love to have a longer version of "Morning Cafe".
All music tracks should be single loops not relooped.Then any novice that can cut and past to create an endless loop of anything. Being a musician helps with this but most people lack that ability. I do appreciate the free stuff but unless you can edit it the odds are very good you aren't going to find the exact length you need.
