I have to admit, I really like Coldplay and OneRepublic. I also really love Creedence Clearwater Revival, even though they were band back in the late 1960s.
I guess you can say that I also like Owl City, Imagine Dragons, Green Day, CNBlue (Korean boy band), Girls Generation (Korean girl group), SHINee (another Korean boy group), P!ink, and Maroon 5.
Sometimes I also listen to One Direction, Taylor Swift Justin Bieber, Jesse McCartney, Bruno Mars, and Austin Mahone, but that's only when I feel like crap because their songs are catchy and their lyrics are either uplifting or suit my crappy mood.
I don't know if you'd consider him an artist (he's more of a composer), but I love listening to and playing music by Dvorak! In my opinion, he's an excellent composer and one of the best of all time! I also enjoy listening to and playing music by Tchaikovsky, Chopin, Bach, sometimes Vivaldi (although his repetitions can get annoying), and occasionally Brahms (when he's not being evil in his music by making you shift from first position to like seventh. If you don't know what that means, that's okay; it's a string player thing). And since I'm a violist (in other words, I play viola), I have to of course appreciate Telemann, Hoffmeister, Bloch, Stamitz, and Alessandro Rolla.
