Song statuses are gained through various methods. Most of them dissapear over time, with the only exception being the GOLD status.
The bonus multiplier affects the song's bonus on your unit's stats. For example Tonari ni has 3 yellow stars, usually that increases your visual score by 30. But if Tonari ni is in gold status, your visual score is increased by 60.
