De Tijdloze on StuBru

De Tijdloze is the all-time list of Studio Brussel, the Flemish rock station. Listeners vote for their favourite songs every year, and since 1987 StuBru has broadcast the top 100 at the end of December. Since 2019 the rest of the vote is known as well: 500 places in 2019, around 2,000 since 2021. A place above 100 did not make the broadcast. The figures come from tijdloze.rocks, an independent site that keeps every list since 1987. Click a column header to sort.
