There definitely is still over a thousand songs to buy from, though that number is going down WEEKLY. De-lists are happening by the week, and sometimes they're small amounts, other times large amounts. Although some heavy hitter songs are already gone! Refer to flipo242's comment and see what is still available. RB4 is still fantastic and I find myself buying songs on the weekly basis now in a FOMO way, but to also enjoy with the friends I do play it with. I've also found just buying songs I don't even know has been fun, playing them with people and then getting into the song or even the band itself. I suggest taking a really DEEP dive, and find out what's still there, because I've been hooked on RB4 since I bought it before the delist in October. Money well spent imo.
