I've looked through this forum and didn't see this suggestion, so I wanted to bring it up:
From Live Patch 1.90 (Sept 5, 2007) -
"Speed, Power, Health, and Endurance songs that require an instrument on Bards and Minstrels are no longer interruptible. "
With only one song being playable at at time, and having to swap from Speed to Endurance mid-fight as a Bard, these songs should not be interruptible. There is good reason this change was made on live, as no other realm deals with this frustration due to their form of the Endurance buffs.
