These girls are not as clever or groundbreaking as they think, in terms of subject matter. Their lyrical skills also leave something to be desired.
That's an awfully negative comment. And what clues you in on just how clever and groundbreaking they think they are? I saw an interview where they essentially said they are just having fun, and acknowledge others who have broken the ground with this type of musical humor. That the music went viral on youtube gave them encouragement. Most of their music is just the two of them sitting on the couch playing uke and guitar while singing, with occasional cuts to other visuals, which suggests to me they are, indeed, just having fun with it. They are both more actresses than musicians, which (to me at least) excuses any shortcomings on the voice end... even though I think they do rather well in their non-professionally produced recordings/videos. Having dabbled myself in producing recordings, I know how hard it is to make singing sound anything close to professional.
