    Fetch albums by artist

First install httpie and jq (pip install httpie, pip install jq).
Save mass-fetch.cmd and get-albums.cmd to one directory.
Then create inputfile.txt in the same directory which could be:
Metallica
"Dream Theater"
Leprous

Then run:
mass-fetch.cmd inputfile.txt

It will read inputfile.txt and process every line with get-albums.cmd and outputs to output.txt file:
Metallica;"Kill ’em All"
