Rare Rock N' Roll Tracks Of The '50s & '60s Vol. 1, 2, 3 & 4

I was not sure where to post this since these songs technically don't belong on the soulfuldetroit forums, but these are posted on youtube in 4 volumes with 80 songs for each volume. I have never heard of any of these songs or artists. Most of them are excellent quality. To be honest, most of the songs sound like they were recorded at the same record company or something. I was wondering if anyone has any info on some of these songs? Are they rare b-sides? Non-hit rare singles? Local record companies from around the country that never made it big? Here are the links:

I was around in the fifties and sixties, but never heard of these songs or artists.
One of them sounds like the Neil Sedaka hit, LITTLE DEVIL.

One of the Guys by Vinnie MOnte above, reminds me of this Neil Sedaka hit
