Is Hindi Film Music in a Renaissance?

Short post - but it seems like Hindi film music is going through an amazing resurgence the last few years. I don't know what is the cause of it...if it is the increasing number of fresh music directors; or the music talent shows sparking a renewed interest; or the influence of Pakistani bands. But I am hearing more and more sweet and well-sung numbers. Most movies now come with a Sufi style song (and an item song, which is another matter).
I have a few personal favorites, such as:
Mitwa from Kabhi Alvidha Na Kehna
Dil De Diya Hai from Masti
In Dino Dil Mera from Life In a Metro
Jab Se Tere Naina from Saawariya
Aaoge Jab Tum Saajna from Jab We Met
Aaj Ki Raat from Don
Woh Lamhe from Zeher


"In dino dil mera" rendered by Debojit Datta in Zee SaReGaMaPa (starting 1:20)


At the same time I am worried about the Tamil music industry. Harris Jayaraj or Yuvan Shankar Raja are pale substitutes for giants such as Ilayaraja and Rahman. Yuvan still has off key singing in his songs. They are going wholesale Western without any attempt at fusion. It is disappointing and it would be nice if we have another music director of the calibre of Ilayaraja...
