Sylly and I ran into each other yesterday in the Karanas (I still have the
bruise) and I was privileged to accompany her on a mission to E Commons.
Among the discoveries made that day (one being that a 14th song Bard is
pathetically slow compared to a 31 with a Mistmoore Battle Drum - thanks for
scarring me for life, Sylly!) was that her Accelerando cancelled mine if we
were both playing it. The higher level song apparently takes over, which was
a good thing in this case, otherwise she'd still be waiting for me. I left
mine on to test, and when we got out of range, I got the message "You Slow
Down". And indeed I did slow down to normal running speed, no boot icon
displayed, even though I was still singing my Selo's. We were out of range
for several seconds one time and my Selo's never kicked in. Now, if I was
playing something else and switched to Selo's it would activate if I wasn't
in her range. So my conclusion is that the weaker song is cancelled until
the next time it is started outside the stronger singer's range. If it is
true, I suspect that other Bard songs probably don't stack, either, like the
heal song. Anyone else test this?

p.s. The best experience was gliding up the Highpass ramp in E Karanas, me
playing Selo's, Sylly levitating us with Aria. Nice to have a taste of the
future, if only for a little while. Thanks, Sylly!
