Can I just say Party in the USA is a classic college song and I'm not insecure in my music taste to post a Miley song. I'd love to say that this is a wonderful pop song and I'd love to give this girl some more support (though I am gunnin' for Liam Hemsworth to move on with his life) but unfortunately I'm underwhelmed by this single. With a basic message that she'll do whatever she wants (which is just partying and dancing?), Miley delivers some decent vocals which get manipulated with some weird robot-reverb-autotuney effect. Also really? You want to shake it like you're at a strip club? Cool, Miley. Cool.
Let's cut the B.S. This has a decent basic melody, it's got a minimalist feel, but I don't think this is gonna be a song that makes me dance in any strip club or get "turned up" to. If anything, this will be remixed by many and will become the dance song it should be.
Take a listen for yourself. I expect more from you, Miley. Hopefully your following singles have a bit more punch.
