Evaluate some Jamendo results which are only 'preview' quality files

[zackkrida]

Description

Unfortunately, Jamendo appears to include two kinds of CC-licensed audio files in their service:

1. Tracks fully licensed using a CC license: https://www.jamendo.com/track/1411230/dogu-comme-demain
2. Tracks where only a lower-quality, 'preview" file is CC licensed, and the higher-fidelity version requires a paid commercial license: https://www.jamendo.com/track/26967/batman-loves-my-dog

The differences between these two tracks are evident in the UI. Here are screenshots of the 'paid' track:

Jamendo refers to the later paid licenses as "official", which sadly seems to imply that CC licenses are somehow "unofficial'. I don't love the spirit of that.

To resolve this, we need to decide:

• Do we think the second type of tracks belong in Openverse?
• Is there a way to differentiate between these types of tracks?
• Can we provide instructions to our users about how to download Jamendo images and navigate this obscure language and UI?

There's an additional point that Jamendo may have removed license filters from its search capabilities.

I've also assigned the "💬 talk: discussion" label here because it seems like there are some questions that we need to discuss and come to a conclusion about.

License filters are broken, so it's probably time to revisit removing it entirely until/unless there's a way to scrape the library, grab the license info, and maintain an index of it. Sad, since I remember a decade and a half ago, it was the best place to go for freely licensed music.

My comment on the linked ticket:

Also, the search returns the "invalid search result: https://www.jamendo.com/search?q=fq" because of the malformed search query.

The malformed query may be due to the fact that the Jamendo site may have been updated and their search query format updated as well, implying that we may need to update ours in return so as to get expected results.

The current state is broken still, and results in queries like so, where the search terms become [query-nc] [-nd] instead of [query] [-nc] [-nd]:

And either way, the filters for removing noncommercial and non-derivative licensed results don't work.

So as it stands, the old Jamendo contains music that can be modified, downloaded, and reused (Personal use).

And the site licensing.jamendo contains music that can be used for commercial purposes and played in public places.

[…] So for example, if the user checked the "use for commercial purposes" checkbox, we redirect to licensing.jamendo else we redirect to old Jamendo

This is incorrect, and therefore the solution implemented in #137 is backwards. Jamendo has adopted the language of the music industry oligopoly: "can be used commercially" actually means you can't use it commercially until you buy a license. "can be used personally" means you can use it personally (and maybe commercially too, but it's not in our financial interest to inform you)

@heyakyra, Openverse collects the data from its sources using their APIs, so we are not affected by the Jamendo UI filters. The data that is already in Openverse has the appropriate licenses that the media used when we ingested it from the API. So, if you want to search for Jamendo audio on Openverse, try searching for cat with 'Use commercially' and 'Modify or adapt' filters applied: https://openverse.org/search/audio?q=cat&license_type=commercial,modification&source=jamendo

The snapshots you shared are from the old "CC Search". If your issue is related to the search on https://search.creativecommons.org/, you should report it in the CC repository.
