Comment 1 for bug 1088269

I can confirm this. And with an even larger library (e.g. mine with approx. 10.000 songs) this makes Noise totally unuseable because it freezes for like 10 minutes every time (media import, start up, smart playlist editing, etc.).

Converting the smart playlist queries into SQL queries is the only sensible way to fix this (and a lot of freezes caused as side-effects).
