Available Markets for some albums returning doubled results

[stewart-wright]

Endpoint(s):

• v1/albums/

Scope(s):

• None (application is not using authentication)

Steps to reproduce:

1. Open the API Console
2. Call the albums endpoint with album_id 64peTvbTLBDeSBu0GsCRE4

i.e. goto this page

Expected behaviour:

An album object with an 'available_markets' field containing a list of unique ISO country codes:

"available_markets" : [ "AD", "AR", "AT", "BE", "BG", "BO", "BR", "CA", "CH", "CL", "CO", "CR", "CY", "CZ", "DE", "DK", "DO", "EC", "EE", "ES", "FI", "FR", "GB", "GR", "GT", "HK", "HN", "HU", "ID", "IE", "IS", "IT", "JP", "LI", "LT", "LU", "LV", "MC", "MT", "MX", "MY", "NI", "NL", "NO", "PA", "PE", "PH", "PL", "PT", "PY", "SE", "SG", "SK", "SV", "TR", "TW", "US", "UY" ]

Actual behaviour:

The above album object, but with the list of country codes duplicated:

"available_markets" : [ "AD", "AR", "AT", "BE", "BG", "BO", "BR", "CA", "CH", "CL", "CO", "CR", "CY", "CZ", "DE", "DK", "DO", "EC", "EE", "ES", "FI", "FR", "GB", "GR", "GT", "HK", "HN", "HU", "ID", "IE", "IS", "IT", "JP", "LI", "LT", "LU", "LV", "MC", "MT", "MX", "MY", "NI", "NL", "NO", "PA", "PE", "PH", "PL", "PT", "PY", "SE", "SG", "SK", "SV", "TR", "TW", "US", "UY", "AD", "AR", "AT", "BE", "BG", "BO", "BR", "CA", "CH", "CL", "CO", "CR", "CY", "CZ", "DE", "DK", "DO", "EC", "EE", "ES", "FI", "FR", "GB", "GR", "GT", "HK", "HN", "HU", "ID", "IE", "IS", "IT", "JP", "LI", "LT", "LU", "LV", "MC", "MT", "MX", "MY", "NI", "NL", "NO", "PA", "PE", "PH", "PL", "PT", "PY", "SE", "SG", "SK", "SV", "TR", "TW", "US", "UY" ],

I haven't figured out why this happens or noticed a pattern with it, but it happens with more than just this one id. Other examples: 6BfdhquO8h8n74ZGTvYVVU, 0ZDX7TUhxIn3S9PzO069hX, 3PEIsRKWPx5w1RSoOnrOoh
