No ads?

[MercuriusM]

I've been using Spotify since around December, and I've been enjoying it thus far. However, I have noticed that I'm getting no ads. I'm not using any third-party software to block this, at least to my knowledge. Perhaps my phone has built-in software blocking ads? I'm just curious why I'm getting nothing at all. I don't have a Premium account, and I don't really want to pay either. This just makes me wonder... Does the Free account simply have a long grace period or what?

I also downloaded the app directly from Google Play, if that helps any?
