Some time ago I wrote about old Telugu songs on youtube:
that "have been recently uploaded on YouTube. Search under VSVutukuri, Mukkamala2020, MadhuraGeetalu, TeluguBoss, vjdnld etc"
All have disappeared. It seems that youtube has a three strikes rule and there were complaints about copy right violations. Those gentlemen have taken a lot of trouble to compile the collections. Sometimes seeing the sceneries, background adds to the attraction of the song. (I was using 'Edukondalavda venkataramana sadduseyaka neevu nidura povayya' from 'Pelli chesi chudu' as a lullaby for my grand daughter. She liked the video more than the song.). I hope that those videos can be resurrected in some site taking due care of the copy right rules.
Some like telugutunnel are still working though erratically. Palleturu has some nice songs, two on 'samkranti', Vemulapalli Srikrishna's 'Cheyeyyi jaikottu telugoda' and Srisri's 'polalananni halaladunni'.
