Hello Victoria,
Thanks for the code change. The big problem though is adding is_home() will remove the player from all homepages for everyone using PowerPress.
We do have a feature on the TODO list that would allow each user to pick if the player appears on the various is_home, is_archive, is_tag, etc... type pages, but it has not been developed. I will mark a note in the comments for this task linking to this forum thread, I think this is optimal feature that you would want ultimately.
Thanks,
Angelo
