To say that today's pop music scene lacks originality is an understatment. Songs sound likeother songs all the time, either intentionally or not. And it doesn't help that the same handful of producers are behind all the biggest hits.

So, I find it funny when people get up in arms when one song's similarity to another is so blatant, you can't ignore it. 

The latest example: Cascada's "San Francisco" which bares a very striking musical likeness to Katy Perry's "California Gurls". While the vocal line is different, the music is pretty much identical. 

And, while it's very ridiculous and obvious, at this point, I have to just shrug my shoulders and ask myself "What's the point of getting upset?" It's disposable pop music that one one will remember in 5 years, so just enjoy it.
