Actually, it's one of those annual sets that's always pleasant but rarely earth-shattering (like Tax Day or Earth Day, both coming soon).
I think one can extend that to most 'themed' sets - about 90% of them range from ok/pleasant to awful (the Giants' opening day set from 2011 comes to mind). Once in a blue moon, we get something awesome, like AL's ode to radio. But yeah, I think radical said at least once something to effect regarding theme sets: Pass
I think it's that way -- hit or miss -- with all 10@10s. One of my favorite AL theme sets was
her nautical show on 12-Oct-10 to commemorate Fleet Week.
A lot of theme sets are related to holidays or other annual events, and when associated songs
become perennials then the concept runs the risk of getting stale. We're seeing that a little
with the St. Patrick's Day sets featuring Irish music. Dave avoided this by taking different
perspectives (songs about green for St. Patrick's Day; Valentine's Day sets about breakups
or sex). Dave also had his regular theme sets like Soul Patrol and Strictly Instrumental, which
are broad enough to offer great variety.
