Building a themed Pandora station is an exercise in frustration. For an example creating a James Bond themed station by picking your favorite Bond themes will have you endlessly thumbing down random soundtrack theme music, 1960s easy listening junk, and seemingly even tracks that are liked on your other stations.
I have come to believe that the music genome via thumbs-up/down is an entirely broken way to discover music, but what alternatives are there? It could help to have some control over the genome selectors, such as limiting the BPM, number of instruments played, or toggling vocals.
Due to the forced repetition on Pandora, I’ve had to thumb-down some artists I like. For one channel it presented me with the 80s pop every time I turned it on, and not the repertoire of those artists, just the same few songs you have to hear on every other commercial radio station.
Attention Pandora: I have strong evidence the Eurythmics, Devo, and others produced more than one track!
