It's been fun watching Basshunter's series of videos.
Isla features in all of them, as do her too blonde friends (one of them seems to be called Nikki69 - more on that when we find out later).
In the first vid Isla has dumped her dweeb boyfriend, but they reunite in a club later. BH himself does not appear.
In the 2nd vid they are all on holiday and they manage to have a big row at the end of the vid over some girl. BH himself appears, as the club DJ.
(When I saw him perform live, I learned he is not just a DJ, he sings the lyrics himself, something which we wouldn't have expected or realised.)
In the 3rd vid, BH takes a central role. He is in a cafe where Isla is the waitress, so invites her to a car event. When she turns up, its appears it's some Fast and Furious style meet and he is a driver. Her current bf is BH's rival, and she is doing the starting.
Of course BH wins, then at the evening party (where he hasn't bothered to change clothes), he starts doing a bit of karaoke and this pulls her.
In the 4th vid, they are all on a skiing holiday a la Last Christmas, and it's a girl singing the song. Not sure if Isla herself sings or she's just eye candy for the vids.
Let's see where he takes his concepts next.
