Longer sets preferred...
Extending the sets also presents an opportunity for something I believe would be an improvement, at least for my AH listening experience. Providing a second stream that is identical to the "now playing", but lagged by ~8-12 hours would give the listener much desired control over their AH experience. Replays do provide a sampling of this; however, with a less predictable schedule, extended sets, download features, and an ever increasing number of contributing DJs, it appears likely replays will be a diminished feature. The added benefit of a second stream is to also offer an option other than tuning out to listeners during a longer set of a mix they find unfavorable.
AH is a global experience, and for many listeners their style preferences and listening availability is dynamic throughout the course of a given day. A superior listening experience has always been presented as a priority at AH, and any option offered for the listener to customize that experience to their schedule and preferences will be an enhancement. I'm an avid fan of AH, and I have provided myself with this feature at some of my locations(still streaming, but analogous to buffering 12 hrs.). It has resulted in an enhanced and adaptable listening experience, something I feel compelled to suggest to others( and a bit self serving since I listen from multiple locations where extended "buffering" isn't convenient). As AH continues to grow, which all excellent communities and services tend to do, customizable experiences help welcome new members as well as maintain the existing community. At some point I'll make an argument the entire station could be more of an "on demand" type of service, but I digress to the experts; everyone at AH who performs great work and provides a superior service to the global community of listeners. Much appreciated!
