the amazing thing about abie Rotenberg is that his songs are amazing both as stand alone nice music to listen to, and as deep thought provoking songs as well. his music has the ability to uplift ones spirit and to bring one closer to hashem.
regarding the poster who wanted to know about dreams come true, it is a diaspora song that was composed by abie for them
regarding the OP , I think that they both are similar in that they are very versatile in their music. they both do happy, sad , deep , and exhilarating music well. countr Yossi is also underrated for the work he did with ohr chodosh ( remember eileh borechev?) not just as a song parodist ( forgive me oh comlink -x, grammarian of the CR, if that is not a real word)
