Looking at our server logs we're only receiving '/api/v4/song/search?api_key=XXXXX' from your curl requests .
I'm guessing you have an issue with the quoting of your url which is causing everything after the first '&' to get interpreted outside of your the curl command.
Try copying and pasting my example using double quotes, adding in your api key, and see if that gets you the result you expect.
curl "http://developer.echonest.com/api/v4/song/search?api_key=$ECHO_NEST_API_KEY&format=json&results=1&artist=GROUPLOVE&title=Ways+To+Go"
