Taylor Swift's re-recorded 'All Too Well' debuts atop Billboard Hot 100

Taylor Swift is celebrating her newly rerecorded version of "All Too Well" being the top song in the country and the longest No. 1 hit of all time.

The tear-jerking ballad dethroned Adele's "Easy on Me," which falls to second place, and debuted atop the Billboard Hot 100 -- Swift's eighth official chart-topper.

"All Too Well" is featured on the recently released "Red (Taylor’s Version)," which offers two versions of the heartbreak anthem -- a regular, radio-friendly shorter song, and the 10-minute epic.

Fans spent years begging Swift to release the latter, which she not only did, but also directed and released a short film to accompany the single.

She also gave it a "folklore" facelift just last week with the "Sad Girl Autumn" remix.

Billboard combined the data from the long, short and the "Sad Girl Autumn" version of "All Too Well," which helped propel the single to the top of the Hot 100. Its new ranking smashes the previous record it held when the song appeared on the chart in 2012 at number 80.

This also means that Swift has accomplished a new feat: She's now the proud creator of the lengthiest song to top the Hot 100, dethroning Don McLean's 8 minute, 37-second "American Pie (Parts I & II)" from 1972.

Swift also is the first artist to send a cover of her own song to the top since Elton John did with his 1973 single, "Candle in the Wind." Two covers of that song, recorded in 1988 and 1997, went on to No. 1.

Billboard notes the last time a cover dominated its Hot 100 was in 2001, when Christina Aguilera, Pink, Mya and Lil' Kim performed Labelle's 1975 hit "Lady Marmalade" for the movie "Moulin Rouge!"
