While the music on "Countryman" might raise the eyebrows of country purists, so will the cover. With green marijuana leaves on a red and yellow background, the cover art makes the CD look like an oversized pack of rolling papers.

The marijuana imagery reflects Jamaican culture, where the herb is a leading cash crop and part of religious rites, but it also reflects Nelson's fondness for pot smoking.

Universal Music Group Nashville is substituting palm trees for the marijuana leaves on CDs sold at the retail chain Wal-Mart, a huge outlet for country music that's also sensitive about lyrics and packaging.
