I can suggest you. It's simple. Just select a new song from 1-50 on the chart. And also select another new song with less than 2 weeks on the charts from 51-100 and let the charts do the rest.

Once you think your song has reached the highest on the chart, use edit option and enter with another new song.. your points will increase

You actually don't have to listen. Just look at the Billboard charts and do a bit of analysis and select two songs.
