whoisdays returns with infectious new single ‘Everything (About Her)’

April 14, 2023 – Today, the Irish artist on everyone’s watch list, whoisdays is rocketing into 2023 with an infectious new single ‘Everything (About Her)’ released via Diffusion Lab / Warner Music Ireland.

David Costello aka whoisdays (previously day_s) has returned with a new direction and a new name, he explains, “I think I just needed a switch up, I have changed my sound a lot, so I thought why not change the name as well? Also, it gets rid of that dumb underscore lol.”

The new indie-pop track ‘Everything (About Her)’ was co-written with Oisin Furlong and Chris Bubenzer AKA Benza, inspired by late 1990s and early 2000s rock, fusing styles from each of their backgrounds to create an earworm of an anthem.  Combining rock guitar chords and disco influences, whoisdays explains, “The song is about wanting only one person, no matter how many others come along or how much you know it won’t work.”

Not only changing his name, the new single sees whoisdays taking a different direction from previous releases….’I think ‘Everything (about Her)’ shows a maturity in my music, I’ve gotten to a stage now where I’m enjoying making music again.  I’m not so pressed on writing in a specific style but instead just enjoying the process of seeing what happens in the studio. The song is fun, that’s what it’s all about.’
