We already knew Fearless was a classic project — after all, Taylor Swift won album of the year at the Grammys for her sophomore set — but what we didn’t know until this week was how many great songs were left on the cutting-room floor back when it was released in 2008.

Along with her new re-recording of the album, dubbed Fearless (Taylor’s Version), Swifties also got six never-before-released “From the Vault” songs. “You All Over Me,” featuring Maren Morris, and the rumor-mill-igniting “Mr. Perfectly Fine” came out first, and then the other four came out with the re-recording on Friday: “We Were Happy” (which includes Keith Urban background vocals); “That’s When,” featuring Urban; “Don’t You”; and “Bye Bye Baby.”

On the latest Billboard Pop Shop Podcast, we take a close listen to the six-pack of “new” songs — and you can listen along with us here:

Train’s 2009 single “Hey, Soul Sister” has been certified diamond by the Recording Industry Association of America as of April 7.

“Hey, Soul Sister” was released August 11, 2009, but the song exclusively debuted on Billboard the day before. It was the rock band’s first single in more than three years and the first single from their fifth album Save Me, San Francisco. The song’s diamond status means it has moved 10 million units. According to the RIAA, one equivalent song unit is equal to a single digital song sale, or 150 on-demand audio and/or video streams.

“Got this today in the cybermail. Thank you everyone for this insanely cool honor,” Train tweeted on Friday. “Soon we play it in person. Love and miss you all.”

Train frontman Pat Monahan took a “weird trip” down memory lane to reflect on the song’s current success in a separate statement via Anti Music. “Hey, Soul Sister being the 49th song certified as a diamond record is such a surreal honor,” he wrote. “Thank you to all of you who own a copy. We all love and appreciate you. What a weird trip it’s been. Here’s to being around each other soon so we can all dance and sing this one loud and together. Love, Pat.”

The song peaked at No. 3 on the Billboard Hot 100 11 years ago on April 9, 2010. “Hey, Soul Sister” was a No. 1 hit on Billboard’s Adult Contemporary, Adult Top 40 Airplay, Rock Digital Song Sales and Digital Song Sales charts. It spent a record 22 weeks atop the AC radio airplay tally, which has since been tied with Ed Sheeran’s “Shape of You” and Maroon 5’s “Girls Like You.” A live version of “Hey, Soul Sister” also earned the group their second Grammy Award in 2011 for best pop performance by a duo or group with vocals; the members won their first Grammy nine years earlier for best rock song for “Drops of Jupiter (Tell Me).”

Streams of DMX’s catalog of songs increased 928% in the United States in the days following his death, according to initial reports to MRC Data. Collectively, his tracks garnered 75.7 million on-demand streams (audio and video combined) on April 9 and 10 – up 928% compared to the 7.36 million they earned on April 7 and 8.

DMX died on April 9 after experiencing a heart attack triggered by a drug overdose. He was 50 years old.

The late rapper’s top five most-streamed songs on April 9-10 were “Ruff Ryders Anthem” (9.59 million; up 973%), “X Gon’ Give It To Ya” (5.79 million; up 900%), “Slippin’” (5.52 million; up 853%), “Party Up (In Here)” (5.20 million; up 941%) and “How It’s Goin’ Down,” featuring Faith Evans (3.52 million; up 691%).

Streams of DMX’s music had increased leading up to his passing, following his hospitalization on April 2. In the days before April 2, his songs were streamed between 700,000 and 1 million times a day. Between April 3 and April 8, they rose to between 3 and 4 million per day.

In terms of music sales, DMX’s collected songs and albums sold 101,000 copies on April 9-11 – up 1,036% compared to the 9,000 they sold on April 6-8.During DMX’s lifetime, he notched 31 hits on Billboard’s Hot R&B/Hip-Hop Songs chart and 15 entries on the all-genre Billboard Hot 100. His first five albums – It’s Dark and Hell Is Hot (1998), Flesh of My Flesh Blood of My Blood (1999), …And Then There Was X (2000), The Great Depression (2001) and Grand Champ (2003) – all debuted at No. 1 on the all-genre Billboard 200 albums chart, making him the first artist to see his first five efforts all begin directly in the top slot.

On the latest Billboard 200 chart (dated April 17, reflecting sales and streaming data in the week ending April 8), DMX’s compilation The Best Of re-enters the chart at No. 73. The set earned 12,000 equivalent album units for the week (up 224%), with the bulk of that sum driven by streaming activity for the album’s songs.
