I would like to have a better understanding of the "Copy To Devices Manually" Option in the Recordings section.
In my case, I am using BandHelper for leading worship at my church. Currently, I have loaded just over 250 songs each with its own PDF chord chart.
I grant access to my account for those who need to learn the songs the preceding week.
This week, I tried a little experiment to see just how practical it would be to add MP3 files to the songs, so I added a dozen or so MP3's, and in each case I selected the "Copy To Devices Manually" Option in the Recordings section. The reason I used the option is not because the individual MP3 are particularly large (they average about 5MB each), but because anyone who has Auto-Sync enabled (default setting) could theoretically end up with 250 MP3's (approximately 1.2GB) hammering their phones, and that wouldn't be a very considerate thing for me to do.
So, the desired scenario would be that if they DO want to hear a recording, they would click on the grayed out recording icon in the song,and it would be downloaded from the BandHelper account to their local device for playing.
For now, I would think my fallback position is to manage the "Copy To Devices Manually" Option for the songs we're singing on a week-to-week basis. I suspect, however, that if the MP3 was already present from Week 1, and then I checked the box, it would not be removed from their device, but at least its better than a 1.2GB surprise.
