Those of us old enough to remember the 1960s pirate radio stations tend to do so through rose-tinted spectacles, although they undoubtedly set in train Radio One and the commercial stations of the early/mid 1970s, but there were some shockers floating alongside Radio Caroline and Radio London. .
Yes, looking back, the pirates were imperfect, but at the time, they were better than anything else on offer.
BBC had Pick Of The Pops, and about another couple of hours of "pop" music - per week.
Radio Luxembourg broadcast in the evening, but many programmes were sponsored by record companies. Therefore they "plugged" what the record companies wanted to sell - and even worse, they often played only part of a song - presumably because the record companies wanted to "advertise" as many records as possible in the available time. (And before the start of pirate radio, Luxembourg output had included some drama & light entertainment programmes, etc.)
If you knew where to find it, AFN Germany had a few good pop / rock programmes in the evening, and played a good variety of music. It was sometimes amusing to hear hippy / underground anti-war songs being played by soldiers - I presume the generals did not listen at that time of night....
Unfortunately, they later dropped local music show production and started to relay the syndicated Wolfman Jack show, which was just standard playlist pop mediocrity.
