I haven't heard the new album yet, but I don't know, she was doing so well just a couple of years ago with IASF, that album was surely fresh and amazing, to me anyway, it made me a hardcore fan and appreciate her older works too.
I do think that those girls might be stealing the spotlight a little bit, specially Rihanna and Nicki, since they can be somehow compared to Bee.
I think Beyoncé's musical style is very defined and particular, and the best example to that is the first single of 4. Just like ayu's music is very characteristic, some people might just get tired/bored of that musical style and look for new fresh things?
I do hope all those people who went to see Bee live will remember what a great artist she is, and support her always
She totally deserves it!
