Good work, Plankton. Every song is at least good, if not great.
My only real critique is I think you should focus more on the beat. All of it is sampled besides the guitar, so do something different. Mix it up. Give us 7/8 time, or a clattering, broken beat, or unusual samples.
So yeah, your guitar parts were fanfreakingtastic, even if the beats behind them were unimpressive at best and plain boring at worst. Good job overall, though.
