May be you have a blog or site about music and you have traffics on them but to be frank adsense does not pays well for music rather it pays lot for keywords like web hosts,forex,weight loss and more but it is difficult to get traffics on these topics so you have a choice that you divert your default visitors to those high paying posts. You can make them convince or compelled to visit those posts because no one says that visitors coming to see music lyrics can not be fat and would not prefer weight loss tips. If you did not get me, you can get more details at my blog musicbid where I used the trick. You might search for musicbid to know the trick practically.
I had over 100 micro niche sites back then making $2-3 each. I don't recommend that method though as it was too much management.
