The problem with Spotify

My freshman year of college, I was introduced to Spotify via facebook. I was pleased that I could listen to whatever songs I wanted whenever I wanted. I didn't even mind that there was an ad about every five songs. After a while, I realized that the ads that were being played were different from the ones originally used, and I felt the new ones were very inappropriate. I decided to stop using Spotify because I didn't have the funds necessary to listen ad-free. Even so, whenever I think about Spotify, that one ad plays over and over in my head.
