Didn’t purchase an album, but it is showing up in my play list. Has my account been compromised?

I checked my iTunes list on today and I have multiple songs from U2 that I did not order. I don’t use Shazam. I don’t download music on my 2 other iPads. How did this happen? I also don’t see that these were purchased on my account. What is going on and should I be worried that my account has been compromised.
