I've been listening to a lot of French bands lately; not necessarily all french speaking bands, but bands and artists from France nonetheless. Tahiti 80 has been around for almost 15 years playing their smooth pop gems all over the world - they actually have a pretty big following in Japan. After I heard their 1999 album "Puzzle" I was hooked. Their music would definitetly be perfect for driving around to under the sun this summer.
On an unrelated note, go out and watch "Knocked Up" - funniest movie in a long time - I promise.
