The logic was a bit different.
Since they had durations like any other spell, the understanding was that they were just spells cast with music instead of magic.
There were also a LOT more of them. By 50 you had about a dozen of them. The cap was 99. And given those two songs could be the same "line" and still stack, the actual count rather than just "upgrade lines" was valid :P
