Interesting concept. I have a couple.
For the song I'd say Sense by the Lightning Seeds. A snappy little pop tune from the 90's.
For a CD I'll add What is Beat by the English Beat. Never fails to get my toes tapping. I'm in a good mood 99% of the time but whenever I need a lift this is where I go. I haven't heard Float On but I'll check it out.
**I checked out Float On on iTunes and I've heard that song many times and it's a good one.**
You're the only other person I've ever known of who knows that group/song. It's a pretty damn good disc and I have to agree with you on that.
This'll probably lose me a lot of credibility here, but there are many times a month where I'm just dreading going to the office in the morning. I burned a single song as my go to disc when I'm really aggrivated:
"The Lion Sleeps Tonight"
I just put that on, and I just can't take my angst seriously anymore.
