Table PlayMePlaylist
TrackId - int
Name - nvarchar
UserId - unique identifier

SELECT           UserId, FirstName, LastName, StageName, Address, CountryId, Brief, Date, Email, (SELECT CommonName FROM Country WHERE (CountryId = PlayMeArtist.CountryId)) AS CountryName,  (SELECT TOP (1) FilePath FROM PlayMeImages WHERE (ArtistId = PLayMeArtist.ArtistId)) ...
