Echonest and Million Song Dataset - out of synch?

[slychief]

Hi!

Using your pyechonest library to access your API it frequently happens that song-ids provided by MSD result in empty responses.

s = song.Song('SOMNXCC12AB0187BE7', buckets=['tracks', 'id:7digital-US'])

Traceback (most recent call last):
File "...", line 153, in
s = song.Song('SOMNXCC12AB0187BE7', buckets=['tracks', 'id:7digital-US'])
File "...\pyechonest-7.1.0-py2.7.egg\pyechonest\song.py", line 72, in init
super(Song, self).init(id, buckets, **kwargs)
File "...\pyechonest-7.1.0-py2.7.egg\pyechonest\proxies.py", line 173, in init
kwargs.update(profile.get('songs')[0])
IndexError: list index out of range

• Does this error indicate that there was no song entity retrieved or is it a bug?
• This behaviour is similar using the track class. Does a 'list index out of range' always translate to 'no results found'?

slychief,

The SO (song) ids in the MSD are from a prior snapshot of Echo Nest data. We are looking at how best to update this to freshen the data. Sorry I can't be more specific at this time, but we recognize it is an issue.
