Thanks for the demo

Yulia sounds bad, Lena sounds great.
Lena should scream (or belt, i didn't know that verb) more often, i like how she sounds.
If Yulia can't sing those parts anymore, Lena should sing them instead.
And i like her scream at the end.
They need to pump up the beat though, i miss the techno-rock sound.
This is just blah.
