This is great stuff! It's more of that french pop/electronica that the band Air is the most famous for. This is Phoenix's 2nd album. The first, United, is also very good and a safe buy.
"Alphabetical" is maybe even better, slightly more up-to-date in sound (where United was just basic and plain) and a bit faster in tempo which I think suits the genre better.
A must have I think. The first 2 tracks, "Everything is everything" and "Run run run" are very catchy.
