MPD playlist generator

// get the length of the array between file: and Id: ($mpdstatus) by getting the key for Id:
// add 1 to the key as it begins at zero
// then chunk the array using the value determined above
// for each song, search the returned array for the fields Title: and Artist: (this is done by the array_search_partial function)
// and this will return the keys
// using the keys, then get the required fields ($songArtist = $song[$artist_key];)
// this returns the full string (Title: Burnin’ Sky) so anything before the colon is stripped using the stripColon function
