Well actually, there is a direct translation: "How do you find his songs?" This sentence can have the same literal or the same figurative meaning as the German sentence. Literally, this translation and the original German could be answered: "Ich google sie." (I google them.) However, the German sentence is apparently more likely to be taken figuratively, while this English sentence is more likely to be taken literally. :-) Or at least more likely than the German sentence is.
