I mean that with Annie Mac, the show was devoted to discussing & playing that week’s hottest record (the show was called hottest record of the week or something). For instance, when lana debuted MAC on that show, we had multiple Lana songs played throughout the show, an interview with Lana and the song was played multiple times itself.
With this show (future sounds with Clara amfo), it’s about playing ‘future sounds’, basically a bit of an alternative chart showcase. They choose a song to be the hottest record and play it once but it doesn’t really mean much. Clara usually just says what she likes about the song and why it’s the hottest record, that kind of thing.
edit: an interview is entirely possible btw, just not 100% I don’t think. I think with it being Lana, they probably would arrange an interview. I doubt Ben/Ed would choose to debut a song on the BBC without some kind of additional promo, not when there’s dozens of other shows that would love to interview her & debut a song.
