it sounds like you might want something to shake things up. find some totally different music. try going through popular music charts from the 2000s. 1990s. 1980s. 1970s. 1960s. 1950s. 1940s. 1930s. 1920s. 1910s. 1900s. 1890s. and so on. you probably won't like all of it, but somewhere in there i'm sure you'll find something that will open up some doors for you
