Some old telugu songs back on youtube

Due to some alleged copyright problems, they keep disappearing but some of my favourites are back:
vacchindoyi samkranti, both Ghantasala and M.S.Ramarao are among the singers, snatches of music reminds me Barsaat music (Palleturu around 1952, and Barsaat 1949?).
aa manasulona aa choopulona; the sort of houses in which I grew up.
cheyetti jaigottu telugoda, a rousing (andhra) nationalist song written by Vemulapalli Srikrishna, later communisi MLA from Mangalagiri.
MELUKO VENKATA RAMANA ; some sort of lullaby.
kulamulo emundira ; Rajanala lights up the screen. Apparently, the Kannada version is still very popular.
chigurakulalo chilakamma; very nice lyrics and clearly Pendyala's music.

These
sites have some video songs and movies.
P.S. Telugu articles by K. Rohiniprasad on Indian Music. A few are on film music.
Shaji Chennai has also some nicearticles on film music.
The following post has somereferences to cross cultural influences even on classical south indian music:

See in particular the passage:
"1. Surprizingly no one mentioned about the very early entry of "western
instruments" into India and Indian classical music. I thought that a
person like UVR, who is well acquainted with Carnatic classical music
would refer to Dikshitar brothers (Muttuswami & Baluswami), their early
exposure to British bands at Fort St. George, Baluswamy's interest in
Violin (and how this instrument got so popularized even replacing veeNa
as accomp. instrument in concerts), paTnam subrahmaNya ayyar's
compositions like "raghuvaMSa sudhaaMbudhi chandrasi" (raaga:
kadanakutoohalam), or Tyaagayya's "SaraSara samaraika" (raaga:
kuntalavaraaLi), etc. etc."
