First, calculate the total cost of the songs per month: $0.75/song * 18 songs = $13.50
Next, calculate the total cost of the songs after 4 months: $13.50/month * 4 months = $54
Add the initial joining fee to the total cost of the songs: $54 + $35 = $89
Therefore, the total amount Lisa will pay after four months is $89.
