Segregation of Tracks from Smartphone and PC

[Drosselbart]

Hi folks

I have one question regarding the possible separation of tracks from my smartphone and my PC. On my smartphone I like to hear audio books and almost never listen to songs etc. I use my PC to listen to music instead, but due to spotify connect my audio book on my smartphone gets "overwritten" by the songs as soon as I play one on my PC. Next time I use my smartphone I need to search for the right track and place within my audio book which is quite combersome.

Does anyone have a solution?

Thx in advance for your help!
