Is the fact that the questioner woke up with a segment of songs she used to listen to on her mind an indication of disobedience or Allah's displeasure with her?

Remembering a sin without relishing it is not an indication of Allah's displeasure or the commission of a sin. However, one must be wary of the whispers of Satan and his embellishment of sin. When remembering a sin, one should try to forget it and not dwell on it, and instead, cultivate remorse and brokenness within oneself to increase good deeds.
