Today we stick with music but leave opera for musicals. This list changes all the time, depending on my mood and what's stuck in my head at the time; however, I noticed I picked all female solos, so perhaps I'll do the men's songs another time.
1) On My Own from Les Misérables
2) Ich gehör nur mir from Elisabeth
3) On the Steps of the Palace from Into the Woods
4) Wishing You Were Somehow Here Again from The Phantom of the Opera
5) Nebe to ví from Johanka z Arku
6) Kann ich einfach geh'n? from Rudolf
7) Okouzlená Sandra from Dracula
8) Irgendwo wird immer getanzt from Mozart!
9) Bohemienne from Notre Dame de Paris
10) My Ship from Lady in the Dark
