Go! Vive a Tu Manera (Argentina)
A little more lighthearted than the other entries on this list, Go! Vive a Tu Manera (also known as Go! Live Your Way) follows what happens when a musically talented girl named Mia earns a scholarship to a prestigious academy. So maybe it's a bit more like Victorious than Blood and Water, but it's got all the drama you would expect from a clash between the new girl and the popular girl (and maybe a few musical numbers as well). You can watch the first two seasons now.
