Songs that sound simaliar to each other

 I would be talking about songs that sounds simaliar to each other the songs are Somebody that I use to know By Gotye and Anxiety by Doechi Those songs Melaty's sound the same but the only difference is one song it about somebody the I use to know and the other is about anxiety.

Now usally different songs sound a lot different from each other the song Somebody I use to know I heard first and that came out before the axiety one.

I wonder if the the artist that sang anxiety copied the artist that sang somebody that I use to know.

Because like CD like Kids bop sing the exact same songs on the radio and some people copy idea's of cartoons to and people who copy people's idea's is not good people so be leaders not follwers.

And copying peoples idea's can get you sued. Like some cartoons do the Charlie Brown refrence and other cartoons copy charlie browns idea's and they should of gotten sued a long time ago.
