sqlite : commit to a previous point in sqlite

I have a table in which I am inserting songs after syncing the device.

So I have a situation like this

.
.
2000 entries
commit 1
.
.
5000 entries
commit 2
.
.
(condition)

After syncing the device I have a condition.Based on (condition) I want to do either commit 1 which inserts 2000 entries or commit 2 which inserts all 5000 entries(including commit 1). Is it possible in sqlite?

On searching I found about savepoints. Is this what I need? or should I use nested begin - commit transactions?

PS : I am a newbie to sqlite.
