Analyzing the rhythm, tempo, down beat, words, etc. it would be an amazing mode for parties or even general listening to have Pandora find a matching song to connect from one to the next. On a drum beat, word or phrase, for example "baby" could be where song A ends and song B begins. This could be padded with some electronic effect or be a smooth transition. It would be a feature that would make Pandora the app of choice for get-togethers or dance-offs. It would be especially fun if someone has an eclectic list of artists and genres. Imagine transitioning from the Carpenters to Eminem to Foreigner. Thanks for reading!
