A panel with music marketers expresses how tough it can be to stick with a campaign strategy -- email or otherwise -- when an artist may alter plans.

"We're trying to control leaks in the music industry, but it makes hard when the artist actually releases it," said Universal Music Group's Anna Lee, referring to a song ahead of time, without a label's approval.

Also, after their fans are buzzing about something on Twitter, they may be inspired to oblige requests, affecting a marketing plan.

Then, some artists are loathe to do any promotion, and others may run into trouble with the law, creating PR trouble leading to delay in an album release.
