Last time I asked this question I specified a genre and nobody answered. So this time just leave any suggestions from any genre EXCEPT rap. I just don't like it. But if you are very music oriented then please leave some titles of alternative music.
Kerli is considered alternative but to me she is a genre all her own. The best songs by her are the Creationist, Strange Boy, Walking on Air, and Tea Party. You should really look into her demos on youtube too, those are even better than her album. Good demos by her are She's In Parties, End of The World, Killerwave, Now Is Not Enough, and Speed Limit.
