No. You should read the rules in the guidelines page which can be found in the main menu under the "Other" section. It clearly states:
"No piracy, no mentioning piracy-related sites, no crack discussion"
"No posting of official Rocksmith 1 or Rocksmith 2014 official content. That means included songs and official DLC. Live versions of official content are also not allowed. Live versions of DLC songs that did not make it over to 2014 from the original Rocksmith are allowed as long as it doesn't copy the original chart. No posting of modifications to official Rocksmith 1 or 2014 tracks, this includes chart changes, tuning fixes, or multi-track versions. "
"On this site, Ubisoft released musical content (such as oDLC or On Disc songs) are not shareable in any form "
"CDLC of Official Songs (ODLC) is not allowed due to licensing. Support Ubisoft and purchase the DLC! "
Downloading any song that Ubisoft released for Rocksmith without paying for it is piracy. This is repeated in many places throughout the site.
