The 50-year-old musician's last album was in 2001 and he spent a long time in the studio perfecting the tracks on his latest 'Everything Changes', reported Contactmusic.
"This album has been written over 10 years. I consider writing, singing and producing a creative endeavour, not a commercial one. Getting it right is more important to me," Lennon said.
"It sort of emerges. You think of a song and then start by putting it down over a cup of tea. Musicians pop by and then it takes on its own life," he added.
"There are diehard Beatles and John Lennon fans who think I have done a phenomenal job - written or sung equally brilliant songs," he said.
"Even (Beatles producer) George Martin said if I wasn't John Lennon's son I'd be far better acknowledged. Half the fans love me and the other half won't give me the time of day. People get locked into their opinions. I do try to understand but at some point I have to let go," he added.
