I use Pandora and Spotify frequently and I realized something. Pandora has advertisements in spurts, and they don't really have just 30 ads playing in a cycle. There is this one commercial about Cremette Pasta and it has came on my Pandora 11 times in one day, and I even counted that. It's that ad and then a Christmas ad and that's it. It is seriously the most annoying thing when I know the ad after hearing it for 1 second into it. Do they do this on purpose so the ad gets stuck in your head? I think that they do it on purpose, but I don't think they should do that anymore. I don't think it helps anything.
