What type of music did you listen to before? If you like rock then i suggest Red, Skillet, and kutless. There are more than that lol but i can't remember any atm. If you like Rap then there is Lecrae, KB, Andy Mineo, Tedashii, Derek Minor. PRo, W.L.A.K., Alex Faith and so on. For Contemporary there is Chris tomlin, Michael W. Smith, Addison Road, Matt, Reddman, Francesca Battistelli. and more !
Hope this helps and gets you started to find more artists.
