We like challenges
Metadata can be really difficult, and sometimes we’re challenged by song titles like “ΔMi−1 = −αΣn=1NDi[n][Σj∈C{i}Fji[n − 1] + Fexti[[n−1]]” by Aphex Twin.
Someone who understands this is Paul Lamere of Sun Labs. Read more about how metadata is handled by music services in his recent blog post. Thanks, Paul, for an interesting analysis!
So, does Spotify use MusicBrainz to clean up their metadata, or are you doing something else?
@plamere: Yes, we use both MusicBrainz and AllMusic for metadata. That specific title was taken from MusicBrainz, obviously. :)
