Macklemore, Pitbull part of star-studded Preakness InfieldFest lineup

When Preakness Stakes organizers held their first InfieldFest four years ago, they booked hard rockers Buckcherry and ZZ Top for concerts.

The live music was part of a new plan for the Preakness Infield. Organizers banned revelers from bringing their own alcohol into Pimlico Race Course.

Attendance suffered anyway, despite performances from some of music's top acts (Zac Brown Band and O.A.R. in 2010, Train and Bruno Mars in 2011 and Wiz Khalifa and Maroon 5 last year).

InfieldFest is back once again this year with, perhaps, its best lineup yet in a festival that takes place Saturday leading up to the 138th Preakness Stakes. Scheduled entertainers Pitbull, Macklemore and Ryan Lewis and Florida-Georgia Line have four of the top 10 songs on "Billboard" Magazine's Top 100 songs chart.

Macklemore and Lewis' "Can't Hold Us" is the number one song in the country. "Thrift Shop," their ode to used clothing, is number 6. Florida-Georgia Line's pop remix "Cruise" with rapper Nelly is number 9. Pitbull's "Feel This Moment" is number 10.

Afrojack, Chevelle and Kristen and the Noise are also scheduled to perform during InfieldFest.
