Want something easy, play some Iron Maiden or Iced Earth, solos are pretty straight forward, and rhythm patterns are distinct, but some can't do em, I don't know why!?
Want something a bit more challenging, learn some sweep picking stuff and some arpeggios, or you can always figure out your own. Its pretty tricky, but impressive. It took me about a week to get, but Ive only been playing a year so Im not the best, so others should get it quicker. Check out some Dream Theater, Children of Bodom, and bands like that solos. Also that Opeth song "The Drapery Falls" is good fun to play. And Iron Maidens Transylvania, an easy solo song.
Have fun
