Bests & Worsts Reviews from Amazon

I really enjoy the beat and lyrics of this song.....right up until they drop the f-bomb. I don't understand why it is even there. I saw that the album had the 'explicit' rating on it as well as the 'Some Nights (Intro)' which is the first song on the album. I figured that was the reason the album had to be rated 'explicit', because of that first song only. None of the other songs in the list have the 'explicit' warning next to them, so I figured they were fine. My son then came and told me that I had bought an explicit song. I thought he was wrong, but after listening to the entire song found out he was correct. I'm a bit old fashioned I guess and don't want my kids hearing the f word on a song that really doesn't need it. I couldn't even find a clean version to replace it with. I really think Amazon should have ratings on songs like this. If you are on the product page it doesn't warn you anywhere that this song is explicit. Very disappointing.
