Lyrics in alternative country might be depressing or about social issues, and often from the heart. They do not follow the clichés sometimes used by mainstream country musicians as often. In other ways, the sounds of alternative country artists do not always have much in common. They can include traditional American folk tunes, bluegrass, and other types of sounds. It can be music that does not sound like mainstream rock or country. This has become even more confusing with "alternative country artists" saying that they do not want to be called alternative country, with more mainstream artists saying they are alternative country, and with people saying that older musicians or musicians from the past are alternative country. "No Depression", the most popular magazine about alternative country, said that it covered "alternative-country music (whatever that is)".
