Well, besides the older greats, like the Beatles, if you are talking about today, who I cannot wait to release a new album- and always anticipate anything new from them- it's gotta be Maroon5!
I listen to country, but there is just something about Maroon5.....
I also like a few pretty new country artists that have gotten really popular this year. The Zac Brown Band, Kieth Nail and Lady Antabellum. They are fabulous!
