It would be nice to be able to skip the "song or artist" part and just write the DNA yourself.
Pandora sometimes does a shallow job of figuring out the DNA of a song. It's impossible for them to tell what you like about the song, and it's likely they'll focus on the wrong aspects. Being able to specify the aspects would solve this problem.
Let users add or remove DNA items. Maybe let them specify priority of these DNA items as well.
FOR POWER USERS:
Only as is easily approachable from a development perspective, suggested interactions * Add music genomes positively (like) * Add music genomes negatively (dislike) * Remove/clean up music genomes (no relevance) * Genome priority rating system? (eg rating in range [100, -100] where 100 means songs must have genome and -100 means songs must NOT have genome)
explicit(-100), instrumental(50), jazzy(80) => jazzy instrumental songs (emphasis on jazzy) which do not include expletives
