Chrystal is a singer-songwriter from Bolton, Lancashire, who writes and produces her own material. Her music is a mixture of modern R&B and alternative pop sang with a Northern delivery. "The Days" is a nostalgic jaunt back into a former romance. This isn't the sort of memory dipped in rose-tinted reverie but one tinged with the smoky haze of late-night mischief: "smoking, wine, and drinking haze," as Chrystal puts it. There's an undeniable yearning here as she beckons her former love interest, hoping they'll "swing around" and chill with her, like old times. Released on October 1, 2024, "The Days" was something of a breakthrough for Chrystal, landing her a spot in the UK Top 75 for the first time. Clearly, the song struck a chord with listeners who shared her hope that they, too, might steal a night or two back from the haze of memory. Chrystal wrote the first version of "The Days" in 2015. "When I made the beat for the song, I wanted it to be something that would go off in the club or at festivals," she told Official Charts. "At the time I was either going to raves or performing at them with my sister so I was paying attention to how the crowd reacted to different parts of a song and took inspiration from that by trying to write a vocal that people could catch on to." "The Days" became a hit a decade after it was written when Chrystal's family and friends persuaded her to upload the song along with a host of other unreleased material. "My sister kept me updated, when it first got a few thousands views, we were buzzing about it!" said Chrystal. "And it just kept growing. My daughter also told me there were trends happening on Snapchat too and I think that crossed back over to TikTok."
