Jimi Hendrix rightfully took the top spot on Gibson.com's new Top 50 Cover Songs of All Time list for his version of Bob Dylan's "All Along the Watchtower."And there's no argument on The Beatles taking second for their hot rendition of the Isley Brothers' "Twist & Shout."  Cream's classic jam on Robert Johnson's "Crossroads" completed the Top 5. The Byrds' version of Dylan's "Mr. Tambourine Man," The Animals intense cover of the traditional blues song "House Of The Rising Sun" and Van Halen's ripping version of The Kinks' "You Really Got Me" also made the Top 10.
