amateur stuff, kid works no imagination into this. he's throwing in beatles with tracks that have been dusted by every every other artist and make this lame; the rhythms don't work. it's not bad party music, but GT made this an art, consolidating the fine line of pop that separated pop and rock from rap and rnb.
mashup should be more than combining songs that fit over one another, it's about layering, sequencing and blurring the lines to create new material.
For a change of pace from "mainstream mashup" try giving this new artist a listen. MR MegalomANiac is a new mashup artist out of Pittsburgh,PA (home of Girl Talk) He takes a more electronic and experimental direction to his mash ups.. just released first album "EarGasm" give it a listen and see what you think
