How to unlock the Shake It Up, Baby! achievement in The Beatles Rock Band - Definitive Guide
You'll want to attempt this achevement with some of the longer songs in the game. Some good choices are Helter Skelter and I Want You (She's So Heavy). Just activate Beatlemania as soon as you have a half bar of energy and rinse and repeat four more times for your achievement.
As soon as you activate Beatlemania five times in a song the Shake It Up, Baby! trophy will unlock.
You need to activate your Beatlemania at least 5 times in any song with the Bass or Guitar. To activate Beatlemania first you must hit the series of white notes in a row to get your bar charged up. Once it is charged up half way, you can use it by pressing the select button or lifting the head of the guitar into the air.
A good song to do this in is I Saw Her Standing There. Do this song on Bass and use your Beatlemania every time you get it half way filled and and hit every Beatlemania note and you will get this trophy at the end of the song.
Another good song is Sgt. Pepper's/With a Little Help From My Friends. You can get it on this song with Medium Guitar if you want. Thanks olsen77 for that heads up. Both are good songs to get this trophy on and you couldn't go wrong with either one.
