I love mandolin and I love rock music, but as much as I love the two, I don't think they should always be combined. Still there are numerous examples of songs that would sound great with a mandolin included. Some of personal choices.
1. Let It Rain by Eric Clapton. Tried the intro and it sounded great.
2.Wish You Were Here by Pink Floyd. Another good one.
3.Where The Streets Have No Name by U2. I'd like to hear a good bluegrass picker on this one.
4.Roundabout by Yes. I'm playing around trying to get the intro, and it's obvious a mandolin would be great on this one.
5.Come On Eileen by Dexys Midnight Runners. It goes perfect.
6.Over The Hills And Far Away by Led Zeppelin. Would be perfect as a substitute for the high guitar notes.
7.Dancing Barefoot by Patti Smith. Probably just a personal choice, but I like the sound.
8.Norwegian Wood by the Beatles. First song I learned but it's perfect.
9.Old Man by Neil Young. Substitute mandolin for banjo.
10.Thick As A Brick by Jethro Tull. Fits in several places in the suite.
