Blogger visual editor settings is now on the left hand side just under "Title" section. I had a bit of trouble changing from compose view to HTML view. It could have been a bit more prominent as people do toggle between normal blog composer view & HTML editor view. Anyways, please take a look at the screenshot below.

Sometimes you just stumble into some particular tune while surfing. Maybe somebody has used a particular music piece or song as a background sound for a video. And you want to listen to that whole song or music. But you don't know the name of it. In that case, https://www.watzatsong.com/en can help you. You just upload the tune, maybe be as short as few seconds or a minute. They have a good user community. Some of them will listen to the tune & they will reply back with the name if they know. And it generally doesn't take long, maybe few hours or a day to get a reply back. There are other quicker ways to find a song name from the tune. But if you are stuck, it can be a good option. I used it several years back. I just happened to open it today. Their community looks as good as it was back then.
