PlaylistItems: list

एपीआई अनुरोध पैरामीटर से मेल खाने वाले प्लेलिस्ट आइटम का संग्रह दिखाता है. किसी प्लेलिस्ट में मौजूद सभी आइटम को फिर से डाउनलोड किया जा सकता है. इसके अलावा, एक या एक से ज़्यादा प्लेलिस्ट आइटम को उनके यूनीक आईडी के हिसाब से भी लाया जा सकता है.

कोटा पर असर: इस तरीके का इस्तेमाल करने पर एक यूनिट की कोटे की कीमत लागू होती है.
