1. The Beatles
Certified Records Sold: 269.6 million
Fab Four is without any doubt the greatest thing that happened in the modern music and claims our list of 10 most successful musical artists of all time without any competition. They hold the record for most number-one hits on the Hot 100 chart with 20. The estimated sales of The Beatles reached a range between 500 and 600 million records and considering their popularity, this may well be close to the truth. The shocking thing is that they only played for 10 years before breaking up. Imagine if they lasted 10 years more.
