Most of the time when I check the "Why this song" info I get the generic "because of specific musical qualities" message that tells me the song matching is happening because of non-genome attributes. I often want to find unexpectedly musically-related tracks, but due to the strength of non-genome matching this is often impossible.
Without this type of feature, it is impossible to start a station of e.g. Star Wars Cantina music that will find instrumental jazz tracks with reed instruments, no guitars, and an upbeat tempo.
I don't want to expose any Genome information. I just want to use Pandora the way I did when it first started.
