Yesterday was the two year anniversary of A Year Without Rain 

 Too bad the era was killed when AYWR wasn't sent for adds, and the fact that not even six months after the album was released,  Who Says was released as a single. 
A fun fact about AYWR is that it never sold less than 10k a week until it's 17th week on the charts, in fact it sold an average of 30,944 per week it's first 16 weeks.  By it's 17th week it had already crossed the 500k mark, making it her fastest album to reach gold. It didn't take her two years like some others 
 
Looking back, 2011 was definitively Selena's year. She sold 
917,428 albums in that year alone. Kiss and Tell sold 124,125 copies in 2011, AYWR sold 257,123  and WTSGD sold 536,180 in those last six months of 2011.
