Very few musicians are suitable for inclusion into Wikipedia.
There are millions upon millions of musicians in the world, but only a small percentage (less than a tenth of a percent) of them are worthy of inclusion into the encyclopedia. The general rule for musicians is that there must be enough reliable, third-party information to demonstrate public interest in the individual. Musicians who satisfy at least one of the items below may merit their own Wikipedia articles, as there is likely to be a good deal of verifiable information available about them and a good deal of public interest in them. This list is not exclusionary, but rather illustrates examples of level of notability required for Wikipedia:
A musician or ensemble (note that this includes a band, singer, rapper, orchestra, hip hop crew, DJ, musical theatre group, etc.) is notable if meeting any one of the following criteria:
* Has been featured in multiple non-trivial published works in reliable and reputable media (excludes school newspapers, personal blogs, etc.).
* Has had a hit on a national music chart in at least one large or medium-sized country.[1]
* Has had a record certified gold or higher in at least one large or medium-sized country.
* Has released two or more albums on a major label or one of the more important indie labels (i.e. an independent label with a history of more than a few years and a roster including several notable performers).
* Has won a major music award, such as a Choice Music Prize, Grammy Award, Juno Award or Mercury Prize.
