Named for a precursor of the pickup truck (the O stands for Olds, who also founded Oldsmobile), REO Speedwagon reached the zenith of their popularity in 1981 with the album Hi Infidelity.
If you do not know what REO Speedwagon sounds like, think of the band "Journey", and that will be close enough most of the time. One exception is the song "In Your Letter", which sounds like 1950's bubble-gum rock, and even includes backup female doo-wop singers. I have to admit that for one of the hits on the album, "Take It On The Run", I had previously only heard covers of the song. I think I like the covers better.
The main problem I have with this album is that it is the kind of music I hear played incessantly on the worst FM radio stations across the country. These are mostly owned by Clear Channel, including Jack FM, which I loathe. REO Speedwagon isn't awful music, it's just bland, and it gets played by radio stations that purport to have wide variety, but don't.
Therefore, my suggestion is to not listen to this album. If you need your dose of this music, there is almost certainly a Jack FM in your town, and REO Speedwagon will be played eventually.
