I also know I reach a maximum amount of times I can hear certain songs, for instance, "Wrecking Ball" by Miley Cyrus. I am SO done with that and I liked that song. They just played it too, too much.
Other songs I can absolutely hear again and again and yes, put on repeat in my iTunes. There are more than a few - "Feel Again" by One Republic, "Longtime Sun" by Snatum Kaur, "Maybe I'm Amazed" by Paul McCartney and "The Cello Song" by ThePianoGuys come to mind immediately.
Then there are my playlists - the playlists I made that even I get sick of. So I skip song after song after song until I get to something I love. I do the same thing on Pandora.
What are your favorites? What can you listen to on repeat? What are you done with?
I'm off to the salon - have an awesome Sunday!
