change agent for sales

It appears that I have written enough articles about music and selling to include a series about the connection.  One of the constants in the music business is that the artists must choose between writing and recording songs that are either consistent with what made them famous (giving their core audience more of what they want) or adapting and creating music which would appeal to a potentially newer audience (and perhaps alienating their core audience.)  I think that Paul Simon chose the latter and alienated everyone!
