Are there any Motown songs from the 1950's?

Yes, Though question is rough.

The Tamla label started in Jan 1959 and the Motown label started in Sep 1959

12 songs were recorded on Tamla with "MONEY" being the most popular (also released nationally on ANNA label) Anna Gordy was Berry Gordy's sister.

1 song was released on the Motown label "Bad Girl" G-1 by "The Miracles" this title was transferred from the Tamla label TLX2207 that had a strange numbering convention and the only recording starting with TLX series. Both recorded/released SEP 1959.
