Mozart, K.20, Motet in G Minor, "God is our Refuge" - don't know really how to deal with this style, pieces with polyphonic texture have always proclaimed an ineffability, a unplummable subtlety that no quick perusal can beggar; nevertheless, my dominant feeling on this was - ain't nothing special.
K. 23, Aria for Soprano and Orchestra, "Consevati fedele" - I guess the Ch'io per virtu d'amore part is kind of interesting, but most of it really not so.

Conservati fedele; Pensa ch'io resto, e peno, E qualche volta almeno Ricordati di me. Ch'io per virtù d'amore, Parlando col mio core, Ragionerò con te.

K.22, Symphony Number 5, Allegro - horny, boring; Andante - better than the previous, but not that interesting; Allegro Molto - alright
