[Mick]

I don't think I could even limit it to 10 groups, much less 10 songs:

Beethoven, Rolling Stones, Beatles, The Who, Three Dog Night, AC/DC, Beach Boys, Michael Jackson, Bee Gees, U2

Songs from outside those groups:

Riders on the Storm, The Doors
House of the Rising Sun, The Animals
What I Like About You, The Romantics
Train in Vain, The Clash
Long Cool Woman in a Black Dress, The Hollies
Bang a Gong, T Rex
Immigrant Song, Led Zeppelin
Happy, Pharell
A Little Less Conversation, Junkie XL
Do You Feel Like We Do, Peter Frampton
Forget You, CeeLo Green
I Wanna Marry You, Bruno Mars
