7.1.2: Is there a way to split my music library into 2, so i can shuffle each one?

On my iPhone 5 (7.1.2) i have 2 genres of music, and i want to split them in two 'librarys' so that i can listen and shuffle only the songs in one library at a time, so i avoid listening to both genres when i shuffle at the moment

is there a way to do this, as i could create 2 seoarate playlists but if i hit shuffle it will mix/shuffle the entire library

thanks

oh my mistake, but i dont want to shuffle a playlist but the whole library, as i have hundreds of songs in each playlist
so it would make things easier if i could split the library into two separate ones?
