Just came back to Europe on a transatlantic Lufthansa flight. I was not having great expectations, when I picked the radio channel called "Club Mix". Compared to AH.FM then my previous experiences with LH and all other airlines have been bad in this category.
I was wrong
Lufthansa offers a good set with many good artists.
Just a tip in case you fly LH in the near future
