I bought this single while in Europe (so it was cheaper than 12 bucks!) However, I bought it cause I downloaded the 29 Palms Vocal Remix of "Pieces of me" a while ago and fell fro it right away, even my friends who like hardcore club music liked it, it's so different and a great remix with Trance elements and the perfect amount of vocals used (1st verse and chorus).
Then I gave "Endless summer" a chance and, christ on a bike! Why wasn't this in the album let alone a single? Honestly, this is better than anything she's done even if I haven't heard a lot from her but this wins hands down as her best song. The lyrics might be a little bit cheesy but anything is better than "You make me wanna lala", right? And they make sense, they tell a story and it's catchy though people might complain it's a bit slow however it's in the same vein of Shadow but not as whiny.
As for the Lala song and the video, they're alright I guess.
