For a lot of years now at it was the US acts that were dominating the music scene in the UK, US and around the world with the likes of Britney Spears, Rihanna, Beyonce, JT, Bruno Mars,Lady Gaga having huge success with smash singles,albums and also touring, where UK acts had success but it wasn't to the same extent as American acts. But when you look at the music scene now the biggest and popular acts in the world right now seem to be Ed Sheeran 1D and Sam Smith. Ed has been huge this year in the UK,US and around the world with hit singles like Thinking out Loud and a huge album. It can't be denied 1D are a phenomenon with huge ticket sales and album sales worldwide. Then there is Sam Smith with huge selling singles like Stay with Me and a hugely successful album. Ed and Sam also jave critical acclaim with grammy nods. Also other acts like Coldplay are selling very well with albums. Also other acts like Calvin Harris has hit after hit single and Mark Ronson has Uptown Funk smashing everywhere Noe. But the only really American act that that is really successful now is Taylor Swift but a lot of her success is concentrated in the US. British acts are hugely successful and popular right now in the music landscape compared to the US who always seemed to have the proper huge artists(excluding Adele)
