It was also included on the Byrds' debut album, Mr. Tambourine Man . Written by Gene Clark, who also sings the lead vocal, "I'll Feel a Whole Lot Better" features some of the Byrds' early musical trademarks, including Jim McGuinn's jangling 12 - string Rickenbacker guitar; Clark's pounding tambourine; McGuinn, Clark, and David Crosby's complex harmony singing; and a country - influenced guitar solo . </P> <P> Although it was initially released as a B - side, "I'll Feel a Whole Lot Better" was itself heavily promoted by Columbia Records during the time that "All I Really Want to Do" spent on the Billboard charts . As a result, the song actually managed to chart in its own right at number 103 . Since its release, the song has become a rock music standard, inspiring a number of cover versions over the years . It is also considered by many critics to be one of the band's, as well as Clark's, best and most popular songs, with Rolling Stone magazine ranking it at number 234 on their list of The 500 Greatest Songs of All Time . </P>
