SHINee's first single "Amigo" from their new repackaged album with the same namesake was released to Korean music downloading sites today.

The song is uptempo and hits harder than what you expect from SHINee (usually r&b). The lyrics and theme seem to be getting more sexy, departing from the cute / innocent theme they used to portray with "Noona is so Pretty."

I have heard some of it... it sounds pretty good...I also read that SHINee will perform this song on October 26th's Inkigayo, the MV should come soon as well. So you guys should be looking out for that....I cant wait to see their video for Amigo.. I hope its good, like the rest of their MV's
