The comedian and broadcaster, who started hosting the coveted slot today, explained that he is looking forward to playing songs that he enjoys.
Holmes exclusively told Digital Spy: "The reason I'm excited to start at Xfm is that they aren't afraid of their own shadow. It's okay to stir things up a bit.
"The best bit is that I can play exactly the music I like, so I won't have to play Michael Kiwanuka just because the BBC told me to and pretend to enjoy it."
Asked if he was nervous about taking over from previous host Danny Wallace, he admitted: "Of course, especially as I tend to make things up as I go along. How could I have said no to it though? The Breakfast Show is the stuff of legends.
On whether Holmes plans to use any of his popular comedy features from his show on BBC 6Music - which have previously included 'The Old Gay Whistle Test' and 'Twittersweet Symphony' - he revealed: "Absolutely - I'm far too lazy to think up new ones! I'll probably use them under a different name.
"That said, we're definitely going to be trying out some new ones on the show and see how they go down. The problem with my ideas is that usually they only half make sense."
Holmes added that he could have made his "smartest move ever" joining station while critics are predicting the return of guitar bands, adding: "For me, it never really went away.
"That said, if you hear complete silence from the station at 6am and I've overslept, then you probably won't hear much from me again."
