That first one sounds like one of the earlier fandom songs. Lots of autotuney goodness. I haven't heard one of those in a while.
And the second is your traditional dubstep! Get both below.
1.) Crystal Slave - Ghost in my Heart (Vocal - Electropop)
2.) NeoN & XAVI - Penumbra (Quadrivia Remix)(Instrumental - Dubstep)
