Every couple weeks??? For a song that reached the number one position on the Billboard Hot 100, and as popular as that song is, most classic hits/classic rock stations would ever play it that inconsistently. It's just not practical. Is that your opinion for most songs as well, or just that particular ditty? I don't mind hearing it every day.
Oh, it's a great song, don't get me wrong. But I have so many other favorites, that hearing it once every week or two is sufficient. I love the song. There once was a time when stations rotated that 6 minute song 3-5 times a day, and it was getting old. Granted, I didn't actually hear it every single time, but to appear on the "last played" list so frequently, gave the impression of overkill. I do have a song collection, so I prefer "spreading out" my musical tastes over a period of time, instead of hearing the same songs again and again.
