OBN Tip
In addition to the main OBN Top 30 chart, another weekly singles chart is published called OBN Tip, it is an indicator ranking of commercially available singles, with positions in the ranking based on a combination of sales and airplay, i.e. the number of times a song is played on radio or television.

OBN Tip differs from the main OBN Top 30 charts in that it depends on both airplay and sales, whereas OBN Top 30 charts are based on sales only. A song cannot appear in the OBN Top 30 based solely on its broadcast figures.

OBN Tip was created in 2006
