2018 was chock-full of amazing songs.
But it's certainly hard to remember all of your favorite releases of the year.
No worries, because this a cappella group from San Francisco sang a 5-minute mashup of every hit song released in 2018.
The Medleycrew's latest a cappella medley features songs like "Friends" by Marshmello and Anne-Marie, "One Kiss" by Calvin Harris and Dua Lipa, and "Shallow" by Lady Gaga and Bradley Cooper. A perfect way for you to recall those few songs that were stuck in your head only months ago.
The Medleycrew has been releasing end-of-year mashups since 2013, so if there's an older song you can't remember, fear not.
This a cappella group created 5 years' worth of similar a cappella medleys. So if that one Katy Perry or Taylor Swift song is on the tip of your tongue, have a scroll through one of their past videos!
Keep rocking on, Medleycrew.
