Okay so I have been following their channel for quite a few years since I chanced upon their first video, Party in the USA. It was really good like how they harmonise and stuff like that and what was shocking to me was that they are actually sisters! (no wonder they look like). What I like about them is really how perfect their harmonisation is and I guess thats why they are so popular now because a capella is what makes them unique. AND they do have alot of originals.. and some are really meaningful if you get the message behind it. One of my favourites is You're Worth It (telling you to be more confident in yourself and not let your low self-esteem bring you down). If you have never heard of them, pls do check them out! To find out more you can go to their website https://www.cimorellimusic.com/ or just go over to their youtube channel or spotify to have a listen.
