Who Me Too'd this topic

I just started using Spotify on my iphone.  I asked my kids which playlist to listen to, and they wanted to listen to Rock Anthems.  After listening to said anthems for the hour commute home (all songs I've heard a million times), my Daily Mixes are affected.  They now have a lot more generic rock songs.

Can I ever play a playlist and *not* have it affect my Daily Mixes?  I know how to delete songs, but it's not something I want to have to do as I listen to the music while I'm driving. 

Like, I might want to listen to Christmas music in December but wouldn't want my Daily mixes infected with Christmas music most of the year.
