Mana mīlākā latviešu dziesma ir Opus Pro "Rozā lietus", jo viņa ir emocionāla, viņa ir ļoti dziļa, un viņa ir pilna ar mīlestību. Šī dziesma ļoti aizkustina, tāpēc arī šī ir mana mīļākā dziesma.
Mani iepriecina un iedvesmo labi cilvēki, kas ir enerģiski un dara kaut ko pozitīvu pasaulei un palīdz attīstīt balsu tehnoloģijas un visādas citādas labas lietas pasaulē.
