Get Cover Art (Online oder iTunes / WMP)

[arne99]

Moin, ich brauche mal eure Hilfe

Ich würde gerne wissen wie ich per API auf existierende Cover Arts von iTunes oder WMP zugreifen kann. Wenn nicht vorhanden, würde ich gern diese per Artist und Title Abfrage aus Amazon greifen.

Gibt es schon Möglichkeiten? bzw. Ansätze? Danke

Edit: Habe soeben ein Python Script gefunden, mag wer Ansätze geben es auf Delphi zu übertragen?[b]
