				"description": "### Display music band with album titles and front covers\n\nThis Postman Collection has a collection variable called MBID (MusicBrainz\n identifier of a band).  \nThe default MBID is that of the British rock band Coldplay,  \n`cc197bad-dc9c-440d-a5b5-d52ba2e14234`.  \n\nTo run the collection, do as follows:\n\n1. _Collections > MusicBands > Dummy-request > *Send*_.\n\n2. If you get the error `Something went wrong [...]`, try clicking **Send**\n again.  \nIf that does not help, try changing to some other MBID. (See below.)\n\n3. In the Postman Response Body, click Visualize.\n\n4. Done! – You should now see the output, displaying the band name and the 15\n first albums, each with its title and front cover.\n\n---\n\nTo change the MBID to some other music band, do as follows:\n\n1. _Collections > MusicBands > Variables_.\n\n2. For the variable MBID, change its **current value** to the new MBID.\n\n3. Click _Save_ to save the new settings of the _MusicBands_ collection.\n\n4. Click _Dummy-request > *Send*_ again to display the information of the new\n MBID.\n\n---\n\nHere are some more MBIDs to try for successful visualizing:\n* cc197bad-dc9c-440d-a5b5-d52ba2e14234  Coldplay (default)  \n* 4b585938-f271-45e2-b19a-91c634b5e396  Kate Bush  \n* 5b11f4ce-a62d-471e-81fc-a69a8278c7da  Nirvana  \n* 0383dadf-2a4e-4d10-a46a-e9e041da8eb3  Queen  \n* 83d91898-7763-47d7-b03b-b92132375c47  Pink  \n* a74b1b7f-71a5-4011-9441-d0b5e4122711  Radiohead  \n* f181961b-20f7-459e-89de-920ef03c7ed0  The  \n* 1a1cd7f3-e5df-4eca-bae2-2757c9e656b5  Duran  \n* 5b11f4ce-a62d-471e-81fc-a69a8278c7da  Vampire Weekend"
