Yes it's what i want to do, because i have made a script Shell which : 1. record a extract of a song (10sec) that is currently played on my computer, and 2. call a python module to search the lyrics that correspond to this song (that's why i have to use track.track_from_filename(mp3)).
And the problem comes from s.get_tracks('musixmatch-WW') which always return an empty list, although i succeed in find the song_id of the track...
When I type in an artist's name, the demo turns up a blank panel.

I tested it out with Eminem, The Beatles, and Madonna.
Hi Wimmer - if you are not logged into the Echo Nest, the demo will use an API key that has a very low rate limit (these keys are often abused, so we keep the rate limit low). This means that they demos often fail, unless you are logged into the Echo Nest as a developer. Log in and try again.

Hi olssonr,
Thank you for bringing this to our attention. We will look into it.
Okay, I've logged in, and it works now!
Thanks for the suggestion:
Tommy W.
Thanks!
Does that mean that the "intended" behaviour of the api is that the sort=song_hotttnesss-desc will try to provide the hottest songs?
If possible, it would be interesting to know roughly when you are planning to deploy this fix, so that i know if I should look into a work around or not.
Is this limit per IP or it is limit in general.
it is a general limit. -- paul
I have taste profiles containing the same 20 songs for every user, but each with the individual song ratings. When I use a taste-profile as a seed-catalog for a playlist, will the song ratings be considered for the playlist generation or do they not matter at all?
it sepends on the playlist type. Song ratings are considered for catalog and catalog-radio playlist types. -- Paul
This is kind of related to this post here.
Say I have a sample of 100 artists, and I take the average term frequencies for rock, pop, and hip hop, and normalize against the average frequency for rock among this sample. Can I then compare these figures to the global term frequencies for rock, pop, and hip hop and reach conclusions along the lines of "the sample of 100 artists has a higher concentration of pop-artists relative to rock-artists than the global population because the sampled (and normalized) frequency for pop is higher than that of the global (and normalized) frequency for pop". Or am I somehow misunderstanding how artist term frequency and global term frequency are related?
Thanks in advance.
acannon - that seems reasonable, but what is your ultimate goal here? There may be an easier way ....

I'm just trying to compare my sampled population of artists (actually 1000 artists) to the global population, analyzing the "randomness" of the sample to evaluate how representative statistical trends within the sample are of the larger artists population. This seemed like a good way to do that.
I have added my music library to tasteprofile (song type) CAPVQY..., every song has item_id as an int64. I have saved those item_ids in local database and hoped, that this will be enough to creating static playlists. Simple playlists works fine
http://developer.echonest.com/api/v4/playlist/static?api_key=UP3xxxx&format=json&type=catalog&seed_catalog=CAPVQY...&artist=Moby&bucket=id:CAPVQY...
But I want also to create playlists based on song. I was so sure, that
CAtalogID:song:item_id
is a correct Rosetta Stone and I thought, that
http://developer.echonest.com/api/v4/playlist/static?api_key=UP3xxxx&format=json&type=catalog&seed_catalog=CAPVQY...&track_id=CAPVQY...:song:4283586156675642324&bucket=id:CAPVQY...
will works, but I'm getting error "track_id - Invalid parameter: "track_id" is not the right type"
Is there any way to ask EchoNest to create playlist based on song identified by item_id in catalog?
You should be using song_id instead of track_id.
I wanted to keep things simple. To use song_ids I must to download them and save in local database or add a query asking for song_id before query with playlist. Echonest already know which song I wanted to use, so why don't use this knowledge?
BTW in description of track_id in Playlist API is written: 'Echo Nest or Rosetta IDs (See Project Rosetta Stone)'. If I use ?bucket:id:CAtalogID Echonest returning with array of CAtalogID:song:item_id, so this is Rosetta ID, but it doesn't works with track_id.
CAxxxx:song:xxxxxxx is a Rosetta song id, not a track id. You should pass it in to the playlist/static call as a song_id argument, not as a track_id argument.
Yes, it works! Thanks.
Is there a way to exclude remixes from a song search with a tracks bucket ? I cannot filter by artist since the foreign artists ids are the same ...
All,
We have discovered an issue where the track/profile call is failing on some tracks when the "bucket=audio_summary" parameter is supplied. This is due to an inconsistency between one of our databases and the deployed API software. We expect this to be resolved today. Thank you for your patience.
